Quite simply, it’s a smooth, comfortable, gliding wrist rest. Resting between your palm and wrist, the Protracker slides around whilst you use your computer mouse, supporting your wrist. No more aching wrists & palms. With Protracker you’re not letting your wrist rest on the solid surface where the mouse is, instead it is sitting on a soft squeeze wrist rest. Protracker will glide & slide in every direction possible whilst sitting comfortably underneath your wrist.
