RollerMouse Pro3 is a classic centred mouse that helps computer users experiencing pain in their upper body (shoulder, neck, wrist, forearm) navigate their computer easily and reliably go through a day of work at the computer without experiencing limiting pain, thanks to the patent protected Rollerbar that provides precise pointer control while keeping the users hands and arms in a natural posture, removing both the need to strain the shoulder to reach for a traditional mouse or the need to grip and manipulate it with the hand and wrist. With its wired connectivity, clearly outlined control buttons and palm rests, RollerMouse Pro3 is the most intuitive and fault proof solution to let computer users work without pain.
