Pain in fingers caused by working for long hours using a standard mouse has been accepted as an occupational hazard. Now no more! The advanced ergonomic design of the puck encourages the natural hand and wrist posture for less fatigue and stiffness in hand during long hour usage. The well designed thumb scoop along with the perfect angle and height of the PUCK allows placing the wrist in a comfortable position to reduce the pressure on the carpal tunnel area of the hand.
