Track Ball Pro, formerly RollerMouse, is a track ball designed with four buttons contained in a small box for individuals who have upper extremity disabilities or who have repetitive motion disorders. The user moves the ball manually to emulate mouse functions. Each button activates an additional feature; these include a "click-lock" feature which allows dragging, scrolling, and drawing without holding a button down continuously, a total left/right control, and multiple resolutions. It is designed as a direct plug-compatible mouse replacement and its easy installation procedure is identical to that of a mouse. COMPATIBILITY: For use on IBM PC or compatible computers, IBM PS/2, Apple Macintosh, or Apple IIGS computers. DIMENSIONS: The track ball is 2.25 inches in size. WARRANTY: Three years.
