Wireless Battery-Free Mouse (Sandberg) 630-86

The Sandberg Wireless Battery-Free Mouse is a wireless optical mouse unlike any other wireless mice. There is no need for tiresome battery changes and slow recharging. What you get is a smart, light mouse without heavy batteries, so you even save the cost of these too. Simply place the mouse on the mouse pad, which is connected to your computer's USB port. The mouse takes the necessary power from the mouse pad via electromagnetic induction. The mouse's optical controls ensure optimal precision, and the wide scroll wheel with ergonomic finger groove makes it easy to scroll through menus and documents.
