Grip Mouse is an ergonomically designed Vertical Mouse that offers value for money compared with many other similar mice. By placing the wrist axis at about 45degrees to the desk surface, the forearm bones are less twisted than with a normal mouse and the circulation is improved from the forearm into the hand. Further the palm area of the hand is supported from the desk rather than resting the wrist. This can assist in reducing muscular discomfort, CTS and RSI in the hand, forearm and upper arm. Comfortable shape with 3-Button and Scroll Wheel with Silver and Black Soft Touch finish. Optical Technology with up to 800dpi and USB Connectivity.
