The RollerMouse Pro has cursor control bar with nearly seven inches of bar access. Contour Design’s RollerMouse Pro ergonomic mouse encourages the equal use of both your hands. With the mouse buttons centered beneath the keyboard home keys, mouse control is equidistant from either hand. The RollerMouse Pro allows you to keep your elbows comfortably by your side, supporting a beneficial ergonomic posture.
There is no gripping necessary with the RollerMouse Pro computer mouse, thus avoiding the threat of Repetitive Strain Injuries (RSI) such as Carpal Tunnel Syndrome and Tendonitis. The RollerMouse Pro is controlled with the use of an unflexed hand, so you do not clutch or grip the mousing device. Your fingertips roll a narrow bar both up and down and from side to side to navigate the cursor over the entire screen, with little friction or resistance.

The RollerMouse Pro has been designed to fit right below your keyboard and/or laptop. Ambidextrous use is encouraged and easily accomplished with your command buttons literally at your fingertips, for both hands. This places the mousing controls just a few inches below the home keys, keeping your hands within a small work area, eliminating large reaching motions as well as asymmetrical reaching. The RollerMouse Pro stops and prevents pain from Repetitive Strain Injuries. Computer users no longer reach twelve to eighteen inches to the side to navigate a traditional mouse, which prevents pain in the neck and shoulder areas. With no hand gripping, hand strain is reduced. The central navigation and button controls promote the use of both hands, which s a substantial ergonomic benefit.
