The Pro Fit Medium Size Mouse from Kensington is a contoured, medium-sized, right-handed mouse that requires no drivers (works plug-and-play), is native USB with PS/2 adapter, and is durable (safe for drops and spills) for long-lasting comfort. Wired and wireless models are available.

The RollerMouse Pro Slim by Contour Design introduces new design features (trayless rollerbar, narrower 15" width) to the Contour Design line of RollerMouse central pointing devices. As with other models the RollerMouse Pro Slim sits immediately between the operator and keyboard space bar. This keeps all mousing activity "inline", i.e., in the area immediately in front of the keyboard, eliminating the need to reach to either left or right for a mouse. This also makes it suitable for situations where there may be insufficient room for a mouse to be placed immediately beside the keyboard. Like all RollerMouse solutions, cursor movement is achieved by manipulating the tube-like cylindrical "rollerbar" with the fingertips. Rotating the rollerbar moves the cursor up and down, and sliding the bar from side to side accomplishes horizontal movement. Once the desired location is achieved, a left click can be generated by pressing down on the bar (the force required for this is adjustable from an ultra-light touch to highly tactile). Eight buttons and a scroll wheel are located below the bar to generate left/middle/right clicks, copy, paste, back, forward and vertical scrolling. There is also a cursor speed button on the left end of the device for accessing ten different speed settings ranging from 600 to 2800 dpi. The RollerMouse Pro also comes with adjustable keyboard "risers" to lift up standard and compact single piece keyboards. Controls can also be heavily customized using the downloadable driver.

The RollerMouse Pro is equipped with a 0.7" diameter smooth-surfaced rollerbar similar to that on the premium RollerMouse Red models. The bar is 7.1" wide and offers a finer degree of control than other models that have bars of a smaller diameter, especially for vertical movement. The new "trayless" design also means that crumbs, dust or debris can no longer collect below the rollerbar but rather drop straight through onto the desk surface for easier cleanup. The robust plastic housing results in a quality sturdy housing. The Vegan Leather palm support attaches magnetically and offers firm cushioning for the heels of the hands and is easily removable for cleaning. The tracking technology on the RollerMouse Pro further enhances cursor control, especially valuable on multi-monitor workstations. All these design elements make cursor control precise and effortless without compromising durability and robustness. The "virtual" clicking mechanism generates a "percussion-free" but audible "click" that can be adjusted in volume or fully disabled if so desired.

The RollerMouse Pro is 15" in width, narrower than most other RollerMouse models. This makes it very suitable for use with compact or compact financial keyboards (such as the Balance Keyboard).
Note: Where a full-width keyboard is being used one of the wider models such as the RollerMouse Red, RollerMouse Pro3, or RollerMouse Free3 should be considered.

La RollerMouse Pro Slim de Contour Design présente de nouvelles caractéristiques de conception (barre de roulement sans plateau, largeur plus étroite de 15po) pour la gamme Contour Design de dispositifs de pointage central. Comme pour les autres modèles, la RollerMouse Pro Slim se place immédiatement entre l'opérateur et la barre d'espace du clavier. Cela garde toute activité de la souris "en ligne", c'est-à-dire dans la zone située juste devant le clavier, ce qui évite d'avoir à s'étirer le bras vers la gauche ou la droite pour bouger une souris. Cette solution convient également aux situations où il n'y a pas assez de place pour placer une souris juste à côté du clavier. Comme pour toutes les solutions RollerMouse, le déplacement du curseur s'effectue en manipulant du bout des doigts le "rollerbar" cylindrique en forme de tube. La rotation du rollerbar déplace le curseur vers le haut et vers le bas, et le glissement de la barre d'un côté à l'autre permet un déplacement horizontal. Une fois l'emplacement souhaité est atteint, un clic gauche peut être généré en appuyant sur la barre (la force requise pour ce faire est ajustable entre ultra léger à très tactile). Huit boutons et une roulette de défilement sont situés sous la barre pour générer des clics gauche/milieu/droit, copier, coller, reculer, avancer et faire défiler verticalement. Il y a également un bouton de vitesse du curseur au bout du côté gauche pour ajuster entre dix différents vitesse de 600 à 2800 dpi. La RollerMouse Pro est également livré avec des "risers" ajustablent pour soulever les claviers conventionnels et compacts d'un seul morceau. Les commandes peuvent également être très personnalisées à l'aide du pilote téléchargeable.

La RollerMouse Pro Slim est équipée d'une barre de roulement à surface lisse de 0.7po de diamètre, similaire à celle des modèles de haut qualité du RollerMouse Red. La barre a une largeur de 7.1po et offre un degré de contrôle plus fin que les autres modèles qui ont des barres d'un diamètre plus petit, en particulier pour les mouvements verticaux. La nouvelle conception "sans plateau/trayless" signifie également que les miettes, la poussière ou les débris ne peuvent plus s'accumuler sous la barre de roulement, mais tombent directement sur la surface du bureau, ce qui facilite le nettoyage. Le boîtier en plastique robuste donne une qualité solide. Le support de paume en Cuir Vegan se fixe par magnétiquement et offre un rembourrage ferme pour les talons des mains; il peut être facilement enlever pour le nettoyage. La technologie de suivi de la RollerMouse Pro Slim améliore encore le contrôle du curseur, ce qui est particulièrement utile sur les postes de travail à plusieurs moniteurs. Tous ces éléments de conception rendent le contrôle du curseur précis et sans effort, sans compromettre la durabilité et la robustesse. Le mécanisme de clic "virtuel" génère un "clic" audible mais sans percussion, dont le volume peut être ajusté ou totalement désactivé si nécessaire.

La RollerMouse Pro Slim a une largeur de 15po, plus étroite que la plupart des autres modèles de RollerMouse. Elle convient donc parfaitement à une utilisation avec des claviers compacts ou financiers compacts (tels que le Balance Keyboard ). Veuillez noter: Lorsqu'un clavier pleine largeur est utilisé, veuillez consideré l'utilisation d'un des modèles plus larges tels que la Rollermouse Red , la Rollermouse Pro3 ou la Rollermouse Free3 .

The Ergo M575 Wireless Trackball from Logitech replaces the earlier M570 Wireless Trackball, offering improved connectivity options. Like its predecessor, the M575 takes most of the repetitive movements and strain which the entire hand usually must perform and allocates all the workload to the thumb. Accurate optical tracking is provided by a laser sensor that offers 400-2000 DPI resolutions. With a contoured body that provides a relaxing support for the hand, the Ergo M575 is equipped with a scroll wheel and right and left click buttons, all positioned as with a traditional mouse. In addition there are Back and Forward Buttons for convenience when browsing through multiple pages. The trackball body is shaped to let the hand rest in a natural relaxed position. As with the earlier M570 model, the M575 is best suited to those with small- or average-sized hands.

Connection can be made via either Bluetooth or the storable USB mini receiver, with a single AA battery providing up to 2 years of service. A battery life indicator will advise when the battery needs replacing. Software available from Logitech offers customization of trackball functions and performance.

Note: As the Ergo M575 places the workload fully upon the thumb, (which on most other trackballs is generally shared amongst several fingers), anyone who has existing thumb issues would be well-advised to consider alternative solutions.

The body of the Pro Fit Wireless Full-Size Mouse from Kensington is contoured for right-handed use and is large enough to provide support and comfort to larger hands. The driver-free Wireless mouse relies on the common 2.4GHz wireless technology (USB only) and works well in all office settings. The Pointer Speed Quick-Select button enables users to quickly switch between 800 and 1200 DPI settings and the back/forward thumb buttons enable rapid navigation within your web browser.

The RollerMouse Go (formerly the RollerMouse Mobile) by Contour Design is a compact version of the well-known RollerMouse Red, designed for mobility and ideally suited for use with compact keyboards. This central pointing device conveniently positions between the operator and keyboard space bar, keeping mousing activity "inline", i.e., in the area immediately in front of the keyboard, and eliminating the need to reach for a mouse. This also makes it suitable for use where there may be insufficient room for a mouse to be placed immediately beside the keyboard. Like all RollerMouse products, cursor movement is achieved by manipulating the tube-like cylindrical "rollerbar" with the fingertips. Rotating the rollerbar moves the cursor up and down, and sliding the bar from side to side accomplishes horizontal movement. Once the desired location is achieved, a left click can be generated by pressing down on the bar (the force required for this is adjustable from an ultra-light touch to highly tactile). Four tactile buttons and a clickable scroll wheel are located below the bar to generate left/middle/right clicks, copy, paste, and vertical scrolling. Cursor speed can be adjusted via a button on the right end of the RollerMouse Go, with ten different speed settings from 600 to 4000 DPI. The RollerMouse Go also ships with two heights of rubber feet that can be used to elevate low profile compact keyboards to better match the rollerbar height. Controls can also be customized using the downloadable driver.

The RollerMouse Go is equipped with the same larger diameter rollerbar found on the RED, as compared to that on the FREE3 or PRO3. On the RollerMouse Go this 0.8" diameter bar is 3.875" wide and offers a finer degree of control, especially for vertical movement. The surface of the bar is textured with raised bumps that offer tactile feedback to further improve all aspects of cursor control. Innovative tracking technology on the RollerMouse Go further enhances cursor control, letting it work equally well on both single and multi-monitor workstations. All these design elements make cursor control more precise and effortless without compromising durability and the robust nature of the sturdy aluminum housing. To further improve the ergonomics even the traditional mechanical "click" has been replaced with a newer "virtual" clicking mechanism that generates a "percussion-free" but audible "click" that can be adjusted in volume or fully disabled if so desired.

Because the compact RollerMouse Go is designed for mobile use it is is able to connect in three ways - to Bluetooth-enabled devices, via a an included 2.4 gHz wireless receiver, or as a wired device via the included charging cable. It also comes with a folding protective sleeve that attaches and closes magnetically.

The optional RollerMouse Go Dock accessory is for those who want the convenience of the more compact RollerMouse Go for travelling but desire the ergonomic benefits afforded by a full-size RollerMouse when they are in the office. The RollerMouse Go simply sockets into the Dock to provide extended palm and wrist support not only directly in front of the RollerMouse Go but also to the right, where a full-size keyboard will have the navigation and numeric keypad. And, when leaving the office, the RollerMouse Go again simply detaches from the dock for full portability.

While the RollerMouse Go and Dock can work perfectly well with any type or size of keyboard those using full-size or separated keyboards may wish to consider one of the full-size RollerMouse Models.

La RollerMouse Go (auparavant la RollerMouse Mobile) de Contour Design est une version compacte de la RollerMouse Red bien connu, conçue pour la mobilité et idéal pour utiliser avec des claviers compacts. Ce dispositif de pointage central se positionne entre la personne et la barre d'espace du clavier, ce qui permet de maintenir l'utilisation de la souris "en ligne", c'est-à-dire dans la zone située immédiatement devant le clavier, et évite d'avoir à s'étirer le bras pour atteindre une souris. Cela le rend également adapté aux situations où l'espace disponible est insuffisant pour placer une souris juste à côté du clavier. Comme tous les RollerMice, le déplacement du curseur est fait en manipulant la « rollerbar » une barre cylindrique en forme de tube avec le bout des doigts. La rotation de la barre à rouleau permet de déplacer le curseur vers le haut et vers le bas, tandis que le glissement de la barre d’un côté à l’autre permet un déplacement horizontal. Une fois l'emplacement souhaité atteint, un clic gauche peut être fait en appuyant sur la barre (la force nécessaire pour cela est réglable de ultra-légère à très tactile). Quatre boutons et une roulette de défilement sont situés sous la barre pour générer des clics gauche / milieu / droit, copier, coller, reculer, avancer et défiler verticalement. La vitesse du curseur peut être ajuster à l'aide d'un bouton situé à l'extrémité droite de la RollerMouse Go, avec dix niveaux de vitesse différents allant de 600 à 4 000 DPI. La RollerMouse Go est également fournie avec deux tailles de pieds en caoutchouc permettant de surélever les claviers compacts à profil bas afin de mieux les adapter à la hauteur de la rollerbar. Les commandes peuvent également être personnalisées à l'aide du pilote téléchargeable.

La RollerMouse Go est équipée de la même largeur en diamètre du barre de contrôle cylindrique que celle de la RED, contrairement à celles des modèles FREE3 ou PRO3. Sur la RollerMouse Go, cette barre de 0.8po de diamètre mesure 3.875po de large et offre un contrôle plus précis, notamment pour les mouvements verticaux. La surface entière de la barre est texturée avec des bosses élever qui offrent un retour tactile pour améliorer encore tous les aspects du contrôle du curseur. La technologie de suivi innovante de la RollerMouse Go améliore encore le contrôle du curseur, ce qui est particulièrement utile sur les postes de travail multi-moniteurs. Tous ces éléments de conception rendent le contrôle du curseur plus précis et sans effort sans compromettre la durabilité du boîtier en aluminium robuste. Pour améliorer encore l'ergonomie, même le "clic" mécanique traditionnel a été remplacé par un mécanisme de clic "virtuel" plus récent qui génère un "clic" sans percussion mais audible, dont le volume peut être ajusté ou entièrement désactivé si on le souhaite.

Parce que la RollerMouse Go compacte est conçu pour les applications mobile/portable elle peut se connecter de trois façons différentes - à des appareils compatibles Bluetooth, via une clé sans fil 2.4 GHz inclus, ou en mode avec fil avec le câble de recharge inclus. Elle est également livrée avec un sleeve de protection pliable qui se fixe et se ferme magnétiquement.

L'accessoire optionnel RollerMouse Go Dock s'adresse à ceux qui souhaitent profiter de la RollerMouse Go, plus compacte, qui est plus pratique durant le transport, tout en bénéficiant des avantages ergonomiques offerts par une RollerMouse de taille standard au bureau. La RollerMouse Go s'emboîte simplement dans le Dock pour offrir un support étendu pour la paume et poignet, non seulement directement devant la RollerMouse Go, mais aussi à droite, là où se trouvent les touches de navigation et le pavé numérique sur un clavier standard. Et, à la fin de la journée, la RollerMouse Go se détache tout simplement du Dock pour une portabilité totale.

Bien que la RollerMouse Go et le Dock fonctionnent parfaitement avec n'importe quel type ou taille de clavier, ceux qui utilisent des claviers standards ou claviers séparées pourraient considérer pour l'un des Modèles RollerMouse à taille standard.

The Pro Fit Full Size Mouse from Kensington is a contoured mouse for right-handed users. This durable USB mouse requires no drivers and comes with a PS/2 adapter. DPI settings can be changed using the switch behind the scroll wheel. Wired and wireless models are available.

The Penguin Ambidextrous Vertical Mouse Wireless from Posturite permits either hand to rest comfortably on the base, while maintaining a relaxed vertical orientation alongside the body of the mouse. Because the hand rests on the base and not on the desk, most movement of the mouse is achieved by employing the larger motor muscles in the forearm and upper arm. However, finer cursor control can be still be achieved with small hand and/or finger movements. The ambidextrous design and central "bow-tie" switch allow for easy transitioning between right and left handed use, encouraging load-balancing use throughout the day. The weight of the hand resting on the base ensures easy movement and control, greatly limiting any need to "grip" the mouse, and permits the fingers to remain relaxed while still being in optimal position for clicking. Features include 4 level adjustable DPI (see Specifications and a precision scroll wheel. The Penguin Mouse is also available in a wired model.

In order to better meet the ergonomic requirements of the broadest range of individuals, the Penguin Mouse is available in 3 sizes - Small, Medium,and Large. This Sizing Chart can assist in determining which model will provide the best fit for those with hands that are evenly proportioned. However, for cases where unusually long fingers or a very broad palm exist, please contact us for sizing assistance.

La Penguin Ambidextrous Vertical Mouse Wireless de Posturite permet à l'une ou l'autre main de reposer confortablement sur la base, tout en maintenant une orientation verticale. Comme la main repose sur la base et non sur le bureau, la plupart des mouvements de la souris sont effectués en utilisant les muscles moteurs plus importants de l'avant-bras et du bras. Toutefois, il est possible d'obtenir un contrôle plus fin du curseur par de petits mouvements de la main et/ou des doigts. La conception ambidextre et le bouton "bow-tie" permettent de passer facilement de la main droite à la main gauche, encourageant ainsi une utilisation équilibrée tout au long de la journée. Le poids de la main reposant sur la base assure un mouvement et un contrôle faciles, limitant grandement tout besoin de "saisir" la souris, et permettant ainsi aux doigts de rester détendus tout en étant dans une position optimale pour cliquer. Parmi ses caractéristiques, le DPI ajustable (400, 600, 800 ou 1200), une molette de défilement de précision, et une couche antimicrobien BioCote à base d'argent). La Penguin est aussi disponible avec fil.

Afin de mieux répondre aux exigences ergonomiques du plus grand nombre de personnes, la souris Penguin est disponible en trois tailles : Petite, Moyenne et Grande. Ce Tableau des Tailles peut aider à déterminer le modèle qui conviendra le mieux aux personnes dont les mains sont de proportion égale. Toutefois, en cas de doigts inhabituellement longs ou de paume très large, nous vous encourageons à nous contacter pour obtenir une assistance avec la taille.

The Wireless USB-C Mouse from Matias is a compact ambidextrous mouse that will fit those with small hands and facilitate load-balancing to reduce RSI risk from using just one hand. Powered by a single AA battery (not included), the 2.4 gHz wireless connection is made through the world's smallest USB-C wireless nano receiver that protrudes just 1/8" from the USB-C port to which it is attached. The small size of the receiver lets it remain attached for immediate connection as soon as the mouse is turned back on. Two DPI settings of 1000 & 1600 can be adjusted from the underside where the power switch is also located.

This hard plastic mouse has a light surface texture that is comfortable to the touch and eliminates the need for the rubberized finish commonly applied to many input devices and which can become tacky over time.

All four switches (Left, Right, Scroll Wheel, and Control) offer a smooth activation with crisp tactile feedback and a quiet but audible click. The lightly-textured aluminum scroll wheel features soft but distinct detents. Just behind the scroll wheel is the control button that functions as a Back button in Windows and can be custom programmed in Mac environments.

The Wireless USB-C Mouse is available in both White and Black and is plug-and-play in both Windows and Mac environments. For convenience it can also share a single USB-C Wireless Nano Receiver with Matias USB-C 2.4 gHz keyboards, making it a convenient partner for data input.

Manufactured primarily for healthcare practices, the Active Key QuickClean Medical Mouse by Contour Design features a sealed covering with an IP68 rating, with a 3-button scroll mechanism. Available in a standard conventional size, the 5-button design and absence of an open scroll wheel readily facilitates thorough sterilization. The impervious silicone sealant that encases the QuickClean Medical Mouse prevents harsh chemicals or liquids from gaining access to the circuitry, an ideal attribute for the severe sanitation protocols present in laboratories or other medical facilities. Even the battery compartment is sealed, with screws to ensure accidental opening cannot occur. The ambidextrous design of the AK-PMH3 QuickClean Medical Mouse can be useful for shared workstations as the mouse accommodates either dominant mousing hand; or individuals that prefer alternating hands. As with all mice, primary buttons can be swapped within the operating system settings.

As the QuickClean is geared towards healthcare facilities, mouse manipulations can be executed with little effort and high precision. The soft silicone housing prevents the hand from slipping out of position, even with medical gloves, encouraging a more relaxed hand both during use and at rest. The compact 5-button layout ensures efficient mouse performance and control, desirable features in time-critical settings. Each button is engineered to only require gentle actuation, while remaining stable enough to prevent accidental clicks.

Often new wired mice tend to re-align or re-adjust the placement of the mouse when the hand is removed. The absence of a cord eliminates the concerns of cord interference, letting the mouse remain in place when transitioning to and from a keyboard.

The Pro Fit Ergo TB450 Trackball from Kensington offers thumb-operated cursor control that eliminates the traditional arm and hand movement required with a traditional mouse. The 45° angled body rotates the hand and forearm away from a prone position to reduce strain on the forearm. Cursor control is via the 34mm trackball which offers silky-smooth movement and adjustable optical tracking from 400-1600 DPI. The contoured body provides a support for the hand, naturally positioning the fingers over the right and left buttons. Vertical and horizontal scrolling function are provided by a tilting scroll wheel that features crisp detents, conveniently positioned between these buttons to complete the traditional mouse control layout. The index finger has easy access to convenient Back and Forward Buttons for browsing through multiple pages of a document or web page.

The Pro Fit Ergo TB450 Trackball offers Dual Connectivity that can simultaneously support connections to up to 3 computers or devices (1 via the included 2.4 GHz receiver and up to 2 more via Bluetooth LE).

As the Pro Fit Ergo TB450 Trackball places cursor control fully upon the thumb, (which on most other trackballs is generally shared by several fingers), anyone who has existing thumb issues would be advised to consider alternative solutions.

Manufactured by Contour Design and intended primarily for healthcare practices, the Active Key QuickClean Medical Mouse with Sensor Scrolling features an IP68 covering. Available in a standard conventional size, the mouse features a 2 button design for left and right clicks, and a central touch zone for scrolling with the swipe of a finger. The impervious IP68 sealant that encases the QuickClean Medical Mouse prevents harsh chemicals or liquids from gaining access to the circuitry; an ideal attribute for the severe sanitation protocols present in laboratories or medical facilities. Even the battery compartment is sealed, with screws to ensure accidental opening does not occur. The ambidextrous design of the AK-PMH3 Medical Mouse can be useful for shared workstations as the mouse works equally well for right- and left-handed individuals; or for those who prefer alternating hands.

The soft silicone housing prevents the hand from slipping out of position, even with medical gloves, encouraging a more relaxed hand both during use and at rest. The compact layout ensures efficient mouse performance and control, desirable features in time-critical settings. The buttons are engineered to require only gentle actuation yet stable enough to prevent accidental clicks. Because the touch scroll function can be less precise this mouse is best suited to more general applications than where high precision movement is required within spreadsheets or similar interfaces. Where those are required the Active Key QuickClean Medical Mouse with button scrolling should be considered.

Often new wired mice tend to re-align or re-adjust the placement of the mouse when the hand is removed. The absence of a cord eliminates the concerns of cord interference, letting the mouse remain in place when transitioning to and from a keyboard.

The OrthoMouse from Orthovia is designed to put your hand in the 'position of function'. When you flex your fingers (i.e. curling your fingers into a ball) you are using the flexor muscles in your hand. When you open your hand (extending your fingers to a straight position) you are using your extensor muscles. The position of function is the point of balance between these two sets of muscles. This design also enhances the tactility of the mouse by using the extra sensitivity in your fingertips to provide maximum precision and accuracy.

The sensor is near the 'top' or tip of the mouse, directly below your fingertips, making the act of targeting and positioning the cursor a direct extension of your fingers (much like writing).

In order to accommodate the various hand sizes, the OrthoMouse comes with several slide-on attachments at the base and top of the mouse to accommodate different hand sizes and methods of use. This ensures an increased sense of tactility and confidence in cursor positioning, resulting in a very small learning curve. This mouse is ideally suited for anyone who is seeking a sense of precision and high tactile feedback including graphics designers and gamers.

Now available in Wireless (see detailed specifications for further details).
Note: Please note that the OrthoMouse replaces the traditional Scroll Wheel with thumb-operated buttons to create a 3-speed scrolling system. Please call for more details on this function.

La OrthoMouse par Orthovia est conçu pour mêtre votre main dans une 'position de fonction'. Lorsque vous fléchisez les doigts (courbé les doigts en rond comme une balle) vous utilisez les muscles fléchisseurs. Lorsque vous ouvrez la main (étendre les doigts jusqu'aux position droite), vous utilisez les muscles extenseurs. La position de fonction est le point de balance entre ces deux groupes de muscles. Ce design renforce aussi la tactiliter du souris en utilisant la sensibilité supplémentaire dans les bout de vos doigts pour permêtre la précision et d'exactitude maximum. Le capteur est proche du haut, ou au point, directement sous le bout des doigts, qui fait l'action cible et position du curseur une extension directe des doigts (beaucoup comme l'écréture).

Afin d'accommoder les tailles de mains variable, la OrthoMouse vient avec des diffèrents attachements qui ce connecte ensemble sur la base aussi qu'en haut du souris pour accommoder les différentes tailles de main aussi que les méthodes d'usage. Cela guarantie la tactiliter et confiance en la position du curseur, qui résulte dans une petite courbe d'apprendisage. Cette souris est, pour la plus part, idéal pour n'importe qui qui regarde pour une sense de précision et plus grande confirmation tactile qui inclu des créateurs graphique et les joueurs (gamers).

Maintenant disponible sans fil (voir les spécifications plus détailler pour plus d'information).

The Kensington Vertical Wireless Mouse angles the hand outwards towards a semi-vertical position in an effort to reduce pronation. A short flange keeps the side of the hand clear of the surface but still permits most of the little finger to make contact during movement. This wireless mouse is contoured specifically for right-handed use and operates plug-and-play. However, optional drivers are available for both Windows and Mac OS should one desire to customize the button functions. A convenient DPI switch accommodates quick access to five DPI settings (800, 1200, 1600, 2000, & 2400) to accommodate different work requirements. The wireless receiver has a 10 metre range and can be stored in the underside of the mouse to ensure it isn't misplaced. The traditional scroll wheel is clickable.

The size of this mouse means it is best suited for smaller or average sized hands. The body is narrower than most vertical mouse designs, which can lead to a tendency to want to "grip" the mouse which has the potential to lead to exerting unnecessary static grip force.
Note: While being identified by the manufacturer as a "vertical" mouse this angle is substantially less than most other "vertical" mousing products, the majority of which orient the hand well above 60° and therefore much closer to a truly vertical presentation.

The rechargeable Pro Fit Ergo TB550 Trackball from Kensington offers thumb-operated cursor control that eliminates the traditional arm and hand movement required with a traditional mouse. The 45° angled body rotates the hand and forearm away from a prone position to reduce strain on the forearm. Cursor control is via the 34mm trackball which offers silky-smooth movement and adjustable optical tracking from 400-1600 DPI. The contoured body provides a support for the hand, naturally positioning the fingers over the right and left buttons. Vertical and horizontal scrolling function are provided by a tilting scroll wheel that features crisp detents, conveniently positioned between these buttons to complete the traditional mouse control layout. The index finger has easy access to convenient Back and Forward Buttons for browsing through multiple pages of a document or web page.

The Pro Fit Ergo TB550 Trackball offers Dual Connectivity that can simultaneously support connections to up to 3 computers or devices (1 via the included 2.4 GHz receiver and up to 2 more via Bluetooth LE).

As the Pro Fit Ergo TB550 Trackball places cursor control fully upon the thumb, (which on most other trackballs is generally shared by several fingers), anyone who has existing thumb issues would be advised to consider alternative solutions.

The MX Vertical Advanced Ergonomic Mouse from Logitech is their first attempt at offering a mouse which more aggressively reduces pronation than other mice in their line. The body of the MX Vertical is angled at a fixed 57° to reduce the risks associated with pronation of the forearm. The angled body is designed to provide the support necessary for the hand to "relax" while engaged with the mouse. However, those with smaller or narrower hands may find that they need to maintain a degree of tension to hold their hands "up" in position over the buttons. Large or wide hands will likely have less of a problem with this requirement to maintain hand position.

The MX Vertical is equipped with a top quality sensor capable of reading from 400 - 4000 DPI. Two nominal settings of 1000 and 1600 DPI can be adjusted anywhere within the range in 50 DPI increments. The top-mounted DPI button enables users to adjust the mouse as needed for basic or fine control movements. The scroll wheel has a rubber tire for grip and features distinct but soft detents. There are 4 programmable buttons (left, right, back, & forward).

The MX Vertical offers 3 connection options: Wired via the charging cord, 2.4Ghz Logitech Unifying Receiver with an operation distance up to 33 feet, and Bluetooth (Bluetooth Low Energy Technology required). The 270mAh Li-Po rechargeable battery can provide up to 4 months use on a single charge and offers a 1 minute Quick Charge that can provide up to 3 hours of use. Of course, individual usage may affect this. Using Logitech "FLOW" users are able to connect to and control up to 3 computing devices using a single mouse.

The "flatness" of the buttons on the MX Vertical prohibit the fingers from achieving a fully relaxed and naturally curved "position of function". This factor, combined with the almost slick surface on the buttons could lead users to try to "pinch" the mouse between the thumb and fingers in an attempt to achieve a better sensation of "control". In addition, to minimize the activation force on the buttons the fingertips need to be as close to the end of the buttons as possible. Those with large hands or very long fingers may be able to achieve this position but most users will find their fingertips falling short of this "optimum" position, resulting in a higher force being required for click activation.

The Pro Fit Ergo Vertical Wireless Mouse from Kensington presents with a body angle of approximately 47°. A short flange keeps the side of the hand clear of the surface but still permits most of the little finger to make contact during movement. This wireless mouse is contoured specifically for right-handed use and operates plug-and-play. However, optional drivers are available for both Windows and Mac OS should one desire to customize the button functions. A convenient DPI switch accommodates quick access to four DPI settings (800, 1000, 1200 and 1600) to accommodate different work requirements. The wireless receiver offers an impressive 20 metre range and can be stored in the underside of the mouse to ensure it isn't misplaced. The scroll wheel is spherical and has a lower protrusion from the body of the mouse than most traditional scroll wheels with rotation being possible using the side of the fingers. Detents provide clear feedback but the smaller diameter of the scroll "sphere" seems to require a greater degree of force than most traditional "wheel" designs.

The size of this mouse means it is best suited for smaller to average sized hands. The body is narrower than most vertical mouse designs, which can lead to a tendency to want to "grip" the mouse which has the potential to lead to exerting unnecessary static grip force.
Note: While being identified by the manufacturer as a "vertical" mouse this angle is substantially less than most other "vertical" mousing products, the majority of which orient the hand well above 60° and therefore much closer to a truly vertical presentation.

The Pro Fit Ergo Wireless Mouse from Kensington presents with a body angle of approximately 40°, rotating the hand away from a traditional fully prone position. This wireless mouse is contoured specifically for right-handed use and operates plug-and-play. It is able to connect via either standard 2.4 GHz wireless with the included receiver dongle, or through Bluetooth 4.0 with devices that can support this option. A switch on the underside changes mode and doubles as a batter-saving power switch. Optional software is available for both Windows and Mac OS should one desire to customize the button functions. A convenient DPI switch just behind the scroll wheel accommodates quick access to three DPI settings (800, 1200 and 1600) to accommodate different work requirements. The wireless receiver can be stored in the underside of the mouse to ensure it isn't misplaced. The scroll wheel has detents to provide clear feedback response. The click action is somewhat soft and very quiet. This lack of tactile and auditory feedback may make it difficult to determine when clicks have truly activated and may lead to a greater degree of force being exerted, resulting in unnecessary stress on the fingers.

The size of this mouse means it is best suited for smaller to average sized hands as those with larger hands will find their palm either unsupported or their fingers extending past the end of the buttons, with the "inset" of the buttons into the body of the mouse making it difficult to perform clicks. The body is fairly narrow as well, encouraging "gripping" rather than permitting larger hands to relax.

Created for those wanting an ambidextrous, wireless mouse with a more traditional look, this mouse offers a symmetrical design and a centrally located scroll wheel. Thumb indentations on both sides of the mouse provide a textured anti-slip surface. The mouse gives left- and right-handed individuals the option of distributing the workload by using the same mouse in either hand.

The Goldtouch Wireless Ambidextrous Mouse has a 1000 dpi optical sensor, and is powered by one or two AA batteries. (Note: Estimated battery life is two months with one battery, and four months with two batteries.) A wireless USB 2.4 Ghz mini receiver is included.

Caution: Those with larger hands may find this mouse too small for all but occasional use.

The Pro Fit Left-Handed Ergo Wireless Mouse from Kensington presents with a body angle of 41°, rotating the hand away from a traditional fully prone position. This wireless mouse is contoured specifically for left-handed use and operates plug-and-play via standard 2.4GHz wireless with the included receiver dongle. Optional software is available for both Windows and Mac OS should one desire to customize the button functions. A convenient DPI switch just behind the scroll wheel accommodates quick access to three DPI settings (800, 1200 and 1600) to accommodate different work requirements. The wireless receiver can be stored in the underside of the mouse to ensure it isn't misplaced.

The size of this mouse means it is best suited for smaller to average sized hands as those with larger hands will find their palm either unsupported or their fingers extending past the end of the buttons, with the "inset" of the buttons into the body of the mouse making it difficult to perform clicks. The body is fairly narrow as well, encouraging "gripping" rather than permitting larger hands to relax.

The Lift Vertical Mouse from Logitech is styled after the larger MX Vertical Advance Ergonomic Mouse. The Lift, designed specifically for small to medium-sized hands, offers the same fixed 57° to reduce the risks associated with pronation of the forearm. The angled body is designed to provide some support necessary for the hand to "relax" while engaged with the mouse.

The Lift Vertical Mouse is equipped with a top quality sensor capable of reading from 400 - 4000 DPI. With a nominal setting of 1000 DPI, the Lift can be adjusted anywhere within the range in 100 DPI increments. The DPI button, just behind the scroll wheel, offers easy access to dpi adjustment for basic or fine control movements. The scroll wheel has a rubber tire for grip and features distinct but soft detents, with the operation almost silent. There are 5 programmable buttons (left, right, back, forward, & middle click).

The buttons on the Lift feature a light curvature to facilitate a more natural curl to the fingers and to provide more control. The left and right buttons require low effort to activate and are almost silent, with the tactile response being a better indicator of switch activation than the sound. However, the hard plastic of the buttons could lead to pinching the mouse between the thumb and fingers in an attempt to achieve a better sensation of control.

The Lift Vertical Mouse offers 2 wireless connection options: 2.4Ghz Logi Bolt Receiver with an operation distance up to 33 feet, and Bluetooth (Bluetooth Low Energy Technology required). It is powered by a single AA battery that the manufacture claims can provide up to 24 months of use (of course, individual usage may affect this). Using Logitech "FLOW" it is possible to connect with and control up to 3 computing devices using a single mouse.
