Anir Vertical Mouse The Anir Vertical Mouse is different from other ergonomic mice - it is designed to be used vertically, in a similar way to a joystick. It encourages users to rest the back of the hand at the base of the mouse and the thumb on the switch on the top of the stick for easy right and left clicks of the mouse button. Using the Anir Vertical Mouse means that the upper arm is used and therefore the strain on the wrist and lower arm muscles is considerably reduced. It has been specifically engineered to help avoid RSI and to offer relief to those already suffering with it. Available in black optical USB large or small. Please specify when ordering. |
