"Asymmetrical reaching with one side of your body and not the other causes your muscle groups to compensate for the weight of your extended arm while reaching for a traditional mouse. Repetitive reaching oftentimes leads to tightness and pain in the neck, shoulder and elbow areas. The RollerMouse Free allows you to keep your elbows comfortably by your side, which is a more beneficial ergonomic position.
The RollerMouse Free is controlled with the use of an unflexed hand, so there is no need to clutch or hold the device in order to navigate the cursor. Your fingertips roll a narrow bar both up and down and from side to side simultaneously to navigate the cursor over the entire screen, with very little friction or resistance. The elimination of flexing your fingers avoids activity through the carpal tunnel; overuse of a traditional mouse can aggravate the carpal tunnel and lead to numbness, tingling and pain.
With the mouse buttons centered beneath the keyboard home keys, mouse control is equidistant from either hand. Ambidextrous use is encouraged and easily accomplished with your command buttons literally at your fingertips, for both hands.
The RollerMouse Free has been designed to fit immediately adjacent to your keyboard or laptop. 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."
