The Goldtouch Semi-Vertical Mouse was created with an optimal slope of 66 degrees for the user who wants a mouse that is midway between a traditional ergonomic mouse and vertical mouse. Unlike vertical mice, you'll have the power of gravity on your side when it comes to clicking, so you won't have to use as much movement between the thumb and fingers (which in turn can require more pinching of your muscles and nerves).
Comfortable Feel: Anti-slip texture grip and rubberized coating provide maximum comfort
Forward/Back Keys: Page forward or Page back with convenient thumb keys
Ideal Slope: 66° slope creates optimal comfort and hand/wrist positioning
Flange Accessory: Detachable Ergo-grip flange keeps palm off the surface of the desk
Plug & Play: Wireless USB 2.4 Ghz receiver allows for quick set up
Adjustable Weights: Four detachable 5g block weights for customized weighting
