Microsoft Wireless Mouse 4000 Black

Carry this compact and sporty wireless mouse, and use it just about anywhere, even on your living room carpet, relying on Microsoft BlueTrack Technology.
Relaxing on the couch or giving a boardroom presentation? Roam up to 15 feet away, and retain reliable wireless control of your computer. Plus, when it’s time to pack up and go, you’ll hardly notice the tiny transceiver.
Keep it plugged into your computer’s USB port, or tuck it into the underside of the mouse for travel.
