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 Bluetooth Ergonomic Mouse from Microsoft is a basic medium-sized mouse designed for right-handed use by those with small to medium-sized hands. The contoured body provides a resting flange for the thumb to discourage the pinching action that many use when moving their mouse. The mouse is equipped with a clickable textured metal scroll wheel that features crisp detents. Two primary buttons offer the standard Right and Left clicks, with two additional thumb buttons for Back and Forward. Microsoft Mouse and Keyboard Center software facilitates custom programming of all buttons, scroll wheel functions, and DPI settings from 400 to 2400.

Bluetooth communication eliminates wire clutter and the ability to pair with up to three Window-based computers and switch seamlessly between them makes the Bluetooth Ergonomic Mouse an appealing option.
Note: Devices must support Bluetooth 4.0 or higher.

For those who prefer the reliability of a wired connection the Ergonomic mouse is also available in a wired version.

The Penclic Mouse (3rd Generation) provides an effortless and intuitive way to move the cursor with fine precision by employing motions similar to those used when writing with a pen. The pen can freely pivot in a recessed circular depression (ball/socket joint) on the base, allowing the user to find the best angle and orientation of the pen to maximize comfort and precision. The base itself glides to provide mouse control, and the movement of the base is achieved by using the small muscles and joints of the fingers as opposed to the larger muscle groups of the shoulder and arm. As the orientation can accommodate a wide range of positions, the user is able to move the mouse with either fine or gross movements (and accompanying positions) which can help to reduce any one set of repetitive movements. The design of the Penclic Mouse (3rd Generation) is also ambidextrous, enabling the user to easily balance the workload between the left and right hands. A number of improvements were made on this latest Penclic such as moving the scroll wheel onto the pen for easier access and better control. The buttons have also been simplified and are more intuitive and easy to use.
