The Sandberg Wireless Vertical Mouse Pro is the ergonomic alternative to a conventional computer mouse. The mouse is tilted to the side and adapted to the profile of your hand. This allows you to move the mouse with a more natural posture. This posture significantly reduces the pressure on your wrist, reducing the risk of pain and joint injuries. For added comfort, the mouse also has a removable magnetic palm rest. It is a wireless mouse. So no annoying cables are needed. Thanks to the built-in battery, you don't even have to worry about changing the battery.
