Nánari lýsing frá framleiðanda:

The Sandberg Wireless Vertical Mouse Pro is an ergonomic alternative to a traditional computer mouse. The mouse is, so to speak, overturned on the side and the shape adapted to the grip of your hand, so that you get a more natural grip of the mouse. This alleviates the pressure on your wrist significantly, and thereby, reducing the risk for pain and joint injuries. Connect the mouse to a USB port in your computer, and it works instantly.
