The HE Mouse Large has a vertical grip which provides a neutral, relaxed position of the hand and wrist. You move from the forearm instead of your wrist, which prevents RSI. The mouse fits comfortably in your hand, and supports your wrist and fingers. You can customize the buttons on the HE Mouse Large to your personal requirements.
