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 Comfort Type Wireless Multimedia Keyboard from Kensington features 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, with full multimedia controls running across the top of the keyboard. It comes with a detachable plastic palm support. It has been tested and provides full plug-and-play functionality under Windows 10.

The StudioMouse Wireless from Kensington is an ambidextrous wireless mouse that features touch scrolling rather than a traditional scroll wheel. Scrolling is accomplished by swiping the finger up or down the touch zone or holding the finger down for continuous scrolling. A middle button just above the touch zone supports auto-scrolling as well. The wireless receiver and charging station connects via USB (for data communication) and a standard wall adapter (for charging). The ambidextrous design makes this suitable for right- or left-handed use. The small dimensions of this mouse (4.5"L x 2.5"W x 1.25"H) make this best suited for those with smaller or average size hands.

This mouse is New Old Stock so the included NiMH rechargeable batteries are untested. However the mouse can use standard AAA batteries. It has been tested and verified to fully function under current versions of Windows.

Basic mouse click functions are plug-and-play but users also have the option of installing the TrackballWorks software for total customization of the 4 large buttons surrounding the ball. Custom and program-specific commands and macros can be programmed for easy completion without the hand leaving the trackball. 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.

Users who prefer a wireless device may wish to consider the Expert Mouse Wireless Trackball which offers all of the same functionality as the Expert Mouse Optical but with the addition of both Bluetooth and standard 2.4 Ghz wireless freedom.

The Expert Mouse Wired Trackball will fit most hands. However, if a user has a small hand they may wish to consider the Orbit Trackball with Scroll Ring which features a smaller 40 mm trackball and is better suited for smaller hands.

The Pro Fit Ergo Vertical Wired Trackball from Kensington offers thumb-operated cursor control that eliminates the traditional arm and hand movement required with a traditional mouse.

The contoured body provides a support for the hand, naturally positioning the fingers over the right and left buttons. Side scrolling function is 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 Vertical Wired Trackball has a hardwired connection that ensures reliable signal for both clicking and cursor control.

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

For those who prefer the freedom of a wireless device this trackball is also available as the Pro Fit Ergo Vertical Wireless Trackball.

The Slimblade Wired Media Control Trackball from Kensington is designed to provide specialized functionality to those working with audio, video, or image editing. Three modes of operation can be accessed. The Slimblade defaults to View mode which offers traditional cursor control and scrolling function; however, Media and View modes can be easily accessed with a single click. The Media mode provides users with quick access to play/pause, stop, and track forward/backward functions while the View mode offers zoom and pan options. A heads-up display on the monitor advises users as to which application is active and what function is being performed.

The Slimblade departs from other Kensington trackball designs by employing a 55 mm trackball which is noticeably heavier for its dimensions than other models. In order to accommodate the need to grip and rotate the ball to accomplish common tasks such as vertical scrolling, 80% of the trackball projects above the housing height, resting freely on top of the trackball base.

Note: While providing users with a stylish look and generous functionality, the Slimblade Media Control Trackball does require repetitive pinching and twisting actions to perform common tasks. As well, the increased elevation of the trackball above the housing can lead to significantly greater wrist extension than other trackball designs. These types of actions and hand placement are often considered potential contributors to the development of complaints such as carpal tunnel or other RSI. Users may wish to consider the intended usage and the degree to which these actions may be required along with any realized benefits when selecting a suitable device.
