Clinically proven to reduce muscle strain and discomfort, the 3M Ergonomic Optical Mouse can help reduce the muscle strain and discomfort associated with carpal tunnel syndrome and repetitive strain injury (RSI)
Using a vertical grip mouse encourages your wrist to remain locked, reducing the pressure on your delicate median nerve. This mouse records optically for smoother, more accurate mousing and has no moving parts to wear out or clean.
