The Kensington Pro Fit Ergo Wired Keyboard features a winglike design that orients the alphanumeric keys at approximately 11° with the navigation and keypad keys being at 0°. This sloping of the keys reduces pronation of the hands and forearm while typing. The left and right key groups are also splayed outwards at 33° to encourage a more neutral alignment and reduce ulnar deviation at the wrists. The integrated palm support on the Pro Fit Wired Keyboard is just over 3" in depth, and offers cushioning for the palms. It is covered in a leatherette material that is easily cleaned.

The angle and height of the Pro Fit Ergo Wired Keyboard is such that the wrists are supported in a fairly neutral alignment when the elbows are about 1" below the desk surface. For those who would rather sit at a more ergonomic height (i.e. elbows at or just above desk height) and benefit from a slight improvement in wrist alignment there are legs built into the underside of the palm support. When deployed these elevate the front to create a nominal 4° negative slope. When the keyboard is flat the highest point on the keys is 1.4" and with the negative elevation legs deployed the highest point is 1.9".

The island-style keys are fairly quiet but it should be noted that they have a moderately high peak operation force of 55 grams, which over time can cause fatigue and strain on the fingers. As well, the inner columns of keys are wider to create a more appealing look but this can lead to inadvertently striking the keys off-centre. When struck to the edge there is a tendency for these keys to partially bind, thus requiring more force to complete the key activation. This could lead to dropped keystrokes and an overcompensation response of exerting a higher degree of force to ensure activation. With a limited travel distance of just 2.5mm this will likely lead to the fingers impacting at the end of each keystroke.

Le Kensington Pro Fit Ergo Wired Keyboard est en forme d'aile (winglike design) qui oriente les touches alphanumériques à environ 11°, les touches de navigation et du pavé numérique étant à 0°. Cette inclinaison des touches réduit la pronation des mains et des avant-bras pendant la dactylo. Les groupes de touches gauche et droite sont également ébrasés vers l'extérieur à 33° pour favoriser un alignement plus neutre et réduire la déviation ulnaire au niveau des poignets. Le support de paume intégré sur le Pro Fit Wired Keyboard mesure un peu plus de 3po de profondeur et offre un rembourrage pour les paumes. Il est recouvert d'un matériau en similicuir facile à nettoyer.

L'angle et la hauteur du Pro Fit Wired Keyboard sont tels que les poignets sont soutenus dans un alignement relativement neutre lorsque les coudes se trouvent à environ 1po sous la surface du bureau. Pour ceux qui préfèrent s'asseoir à une hauteur plus ergonomique (c'est-à-dire les coudes à la hauteur du bureau ou juste au-dessus) et bénéficier d'une légère amélioration de l'alignement des poignets, il y a des pieds qui sont intégrés sous le support de paume. Lorsqu'ils sont déployés, ils élèvent l'avant pour créer une pente négative nominale de 4°. Lorsque le clavier est à plat, le point le plus haut des touches est à 1.4po et lorsque les pieds d'élévation négative sont déployés, le point le plus haut est à 1.9po.

Les touches de style "island" sont assez silencieuses, mais il devrait être noter qu'elles ont une force de frappe significativement élevée de 55 grammes, ce qui, après un bout de temps, peut causer de la fatigue et des tensions sur les doigts. Également, les colonnes intérieures des touches sont plus larges pour créer un apparance plus intéressant, mais cela peut causer de frapper les touches sur le côté par accident au lieu du centre des touches. Lorsque les touches sont frappées sur le côté, elles ont tendance à se coller partiellement, ce qui nécessite une plus grande force pour compléter l'activation de la touche. Cela peut causer les caractères d'être perdus et une réponse excessive qui nécessite plus de force pour assurer l'activation de la touche. Avec une distance de déplacement limitée à 2.5mm, les doigts risquent d'avoir la vibration/choc de l'impact à la fin de chaque frappe.

The Orbit Optical Trackball from Kensington is an ambidextrous alternative to traditional mice which require a constant grip to be used and a larger amount of space on the desktop. The 40 mm trackball utilizes optical tracking for accuracy and is centrally positioned for ease of movement by the fingers. Left and Right buttons are located adjacent to the ball, with the thumb and pinkie fingers naturally dropping into position over them. The Orbit Optical Trackball is sized to best fit the needs of those with small to average sized hands. Individuals with larger hands may wish to consider one of the larger trackball options.

Note: Those who perform large amounts of scrolling need to be aware that the Orbit Optical Trackball does NOT have a mechanism to perform vertical scrolling and should consider a trackball which includes a dedicated scroll wheel or ring such as the Orbit Optical Trackball with Scroll Ring.

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.

Le Pro Fit Ergo Wireless Keyboard peut se connecter soit par Bluetooth 4.0LE ou par un clé USB 2,4 GHz inclus (remplaçable si perdu) qui utilise un cryptage AES 128 bits de niveau gouvernemental pour la sécurité. La connexion peut être facilement changer grâce à un bouton situé sous le clavier, qui sert également au bouton Connect/Off.

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 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 Kensington Pro Fit Ergo KB675 EQ TKL Rechargeable Keyboard is a tenkeyless layout that features the same winglike design as the full-size Pro Fit models. The alphanumeric keys are oriented at approximately 11° with the navigation and arrow keys being at 0°. This sloping of the keys reduces pronation of the hands and forearm while typing. The left and right key groups are also splayed outwards at 33° to encourage a more neutral alignment and reduce ulnar deviation at the wrists. The integrated palm support on the Pro Fit Ergo KB675 is just over 3" in depth at the middle, and offers cushioning for the palms. It is covered in a leatherette material that is easily cleaned.

The angle and height of the Pro Fit Ergo KB675 tenkeyless keyboard is such that the wrists are supported in a fairly neutral alignment when the elbows are about 1" below the desk surface. For those who would rather sit at a more ergonomic height (i.e. elbows at or just above desk height) and benefit from a slight improvement in wrist alignment there are legs built into the underside of the palm support. When deployed these legs elevate the front to create a nominal 4° negative slope. When the keyboard is flat the highest point on the keys is 1.4" and with the negative elevation legs deployed the highest point is 1.9".
Note: While this keyboard does bear great similarity in appearance to the Sculpt Ergonomic Desktop Keyboard from Microsoft it should be noted that the concave layout of the Microsoft keyboard positioned the hands at a lower point than does the Ergo KB675 which has a convex curve to the key layout. As well, the addition of video conferencing keys at the top moves the hand about 0.75" lower on the keyboard which may cause the right hand to want to slip down and off the palm support.

The island-style keys are topped with flat keycaps that have very distinct edges. The key action is fairly quiet but it should be noted that they have a moderately high peak operation force of 55 grams, which over time can cause fatigue and strain on the fingers. As well, the inner columns of keys are wider to create a more appealing look but this can lead to inadvertently striking the keys off-centre. When struck to the edge there is a tendency for these keys to partially bind, thus requiring more force to complete the key activation. This could lead to dropped keystrokes and an overcompensation response of exerting a higher degree of force to ensure activation. With a limited travel distance of just 2.5 mm this will likely lead to the fingers impacting at the end of each keystroke.

This keyboard includes a bank of 4 dedicated video conferencing keys (End Call, Camera On/Off, Share/Stop Sharing, and Mute On/Off). There are also dedicated keys for Calculator, Search, Show Desktop, and Screen Shot, while the F Keys support Media Control alternate functions. In the middle of the keyboard are RGB Battery Status, Caps Lock, and BT Connection LED indicators. There are 20 programmable keys that can be accessed using the Kensington Konnect software - (PC and Mac options available) - that facilitates Key Mapping, Macro Programming, etc.

The Pro Fit Ergo KB675 EQ TKL Rechargeable Keyboard is Windows and Mac compatible and is able to connect via either Bluetooth 4.0LE or the included 2.4GHz wireless receiver (replaceable if lost) which employs 128-bit AES government-grade encryption for security. The connection is switchable via the dedicated "Connection" key.

Le Kensington Pro Fit Ergo KB675 EQ TKL Rechargeable Keyboard est un clavier avec disposition tenkeyless qui présente le même design en forme d'aile (winglike) que les modèles full-size Pro Fit. Les touches alphanumériques sont orientées à environ 11°, tandis que les touches de navigation et les touches fléchées sont à 0°. Cette inclinaison des touches réduit la pronation des mains et des avant-bras pendant la dactylo. Les groupes de touches gauche et droite sont également ébrasés vers l'extérieur à 33° pour favoriser un alignement plus neutre et réduire la déviation ulnaire au niveau des poignets. Le support de paume intégré sur le Pro Fit Ergo KB675 a une profondeur d'un peu plus de 3 pouces au milieu et offre un rembourrage pour les paumes. Il est recouvert d'un matériau en similicuir facile à nettoyer.

L'angle et la hauteur du Pro Fit Ergo KB675 tenkeyless keyboard sont tels que les poignets sont soutenus dans un alignement relativement neutre lorsque les coudes se trouvent à environ 1po sous la surface du bureau.

Lorsque le clavier est à plat, le point le plus haut sur les touches est de 1.4po et lorsque les pieds d'élévation négative sont déployés, le point le plus haut est de 1.9po. Veuillez noter: Bien que ce clavier ressemble beaucoup au Sculpt Ergonomic Desktop Keyboard de Microsoft, il doit être noter que la disposition concave du clavier Microsoft positionne les mains à un point plus bas que l'Ergo KB675, dont la disposition des touches présente une courbe convexe. Également, l'addition des touches video conferencing en haut du clavier déplace la main environ 0.75po plus bas sur le clavier, ce qui peut amener la main droite à vouloir glisser vers le bas et n'est plus sur le support de paume.

Les touches de style "island" ont des capuchons plats qui ont des bordures très distincts. Les touches sont assez silencieuses, mais il devrait être noter qu'elles ont une force de frappe significativement élevée de 55 grammes, ce qui, après un bout de temps, peut causer de la fatigue et des tensions sur les doigts. Également, les colonnes intérieures des touches sont plus larges pour créer un apparance plus intéressant, mais cela peut causer de frapper les touches sur le côté par accident au lieu du centre des touches.

La connexion est switchable par la touche spécifique "Connection".

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.

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 SoleMate Comfort Footrest from Kensington features a 0.375" thick memory foam pad to absorb shock and ease the strain on tired feet. The SoleMate is height adjustable through 7 settings ranging from 4.0" to 5.0" when flat and from to 5.25" to 6.75" at the rear when fully angled, with an adjustable tilt range from 0° through 18°. The innovative foot-activated lock system permits individuals to adjust and lock the tilt at any point within the adjustment range without needing to leave their chair. Height adjustment to meet individual need is done manually via hand.

Note: Due to the nature of this product there is no 30 day CSG.

Kensington has taken their venerable Expert Mouse Optical to a new level with the new Expert Mouse Wireless Trackball. Longtime or novice trackball users now have the freedom of wireless available in a full-size trackball with the additional option of selecting whether to connect via Bluetooth 4.0 LE or traditional 2.4 GHZ wireless using a USB nano receiver. This unique dual-connection feature makes the Expert Mouse Wireless Trackball a good choice for those with a limited number of USB ports or who wish to use the trackball on multiple systems, employing Bluetooth on one and using the RF Receiver on a second or non-Bluetooth compatible system.

The Expert Mouse Wireless Trackball employs Diamond Eye optical technology for smooth, precise tracking and features the well-known Kensington Scroll Ring for quick scroll access on web pages and within lengthy documents. Four large buttons provide easy access to primary functions and can be easily customized to personal preferences through the Kensington TrackballWorks software. The ambidextrous design easily accommodates both right and left-handed use and includes a detachable rest to aid users in maintaining a more ergonomic neutral wrist alignment.

This A-Style Slanted KeyCap Keyboard from Kensington employs specially-designed slanted keycaps arranged in an "A" pattern. This slanted "A" layout of the keys provides a psychological and visual cue to help typists reduce ulnar deviation, minimizing adaptation time. This keyboard features a traditional 103 key layout. The A-Style layouts can be viewed in greater detail on the Detailed Specifications page.
NOTE: These are "legacy" products and are equipped with PS/2 connections. Testing indicates that they may also function with some PS/2 to USB adapters.

The Orbit Trackball with Scroll Ring from Kensington is an ambidextrous alternative to traditional mice which require a constant grip to be used and a larger amount of space on the desktop. The 40 mm trackball features optical tracking for accuracy and is centrally positioned for ease of movement by the fingers. Left and Right buttons are located adjacent to the ball, with the thumb and pinkie fingers naturally dropping into position over them. The convenient Scroll Ring surrounds the base of the trackball and provides fingertip control of scrolling, from line-by-line to speeding through pages. The optional TrackballWorks programming software permits customization or reassignment of the buttons and offers advanced scrolling control options.The Orbit Trackball with Scroll Ring is sized to best fit the needs of small to average sized hands. Users with larger hands may wish to consider one of the larger trackball options.

Three angle settings to help prevent lower back pain. Textured platform (18" x 14") to help massage tired feet. Non-slip feet enhance overall stability.

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 Orbit Wireless Mobile Trackball from Kensington is a compact ambidextrous trackball mouse that provides the convenience of wireless in a small footprint. The compact size and wireless convenience make it a suitable solution for short-term mobile usage or for users with small hands who may find other trackball options to be a bit large.

The Orbit Wireless Mobile Trackball is plug and play (no driver required). Buttons situated on the outer sides of the trackball housing provide access to Left and Right Clicks.

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.
