The RollerMouse Free utilizes a rollerbar that controls the cursor and can be manipulated with either the thumbs or the fingertips, requiring no gripping. The RollerMouse Free also helps eliminate repetitive reaching for a mouse, trackball or touchpad because its controls are centrally located beneath the space bar. Features Include: · At 10.25 inches in length the RollerMouse Free's RollerBar is 3.5 inches longer than the RollerMouse Pro, accommodating a wide range of shoulder widths, thereby, reducing ulnar deviation. · Eliminates reaching for a traditional mouse, relieving neck, shoulder and elbow pain. · Revolutionary rollerbar provides single finger point and click functionality. · There is no gripping necessary, thus avoiding the threat of Repetitive Strain Injuries such as Carpal Tunnel Syndrome and Tendonitis. · Promotes the equal use of both hands, reducing the risk of injuring your dominant "mousing" hand. · Seven powerful button functions right out of the box. There are two easy options to perform a "left click." Either push down on the navigation bar itself, or click on the large left button in the button control area. Other button functions include a traditional "right click" button, a single touch "double click" button, a scroll wheel, a scroll lock , "one touch" copy and "one touch" paste. · Attachable palm supports promotes neutral wrist posture. · The RollerMouse Free comes with detachable keyboard 'risers' which help elevate slim keyboards to a height which prevents accidental movement of the rollerbar. Three height settings are available: 0.25", 0.375", and 0.5".
