The Roller Mouse Pro is a different type of mouse designed to relieve stress on your hands on wrist. The Rollermouse places your mouse just below your keyboard, so to use the mouse you would simply slide your arms down the desk slightly rather than removing your whole arm and moving it off the side of your keyboard where your mouse is normally placed. These repetitive reaching motions can cause strain on your muscles, tendon and joints. The Rollermouse can help to prevent those types of injuries.
