Unimouse is designed with your comfort in focus, also for your left hand! The ergonomic shape reduces the strain on your hands and wrists, allowing you to work without discomfort. With the patented articulated hinge, you can adjust the angle of the Unimouse to any position from 35 to 70 degrees. The friction-based locking system is easy to use and stable in any position. It features 6 programmable buttons that can be set to virtually all functions, meeting your unique needs. The adjustable thumb support can be adjusted in all directions, in/out, up/down, forward/backward, tilt and rotation. This reduces grip pain and pressure on the base joint of the thumb, thereby reducing strain injuries, and you can hold the mouse relaxed - no matter the size or shape of your hand.
