Product Description:
This handy optical mouse features a tiny snap-in receiver that plugs into your notebook when you're ready to work, and snaps into your mouse when you're ready to roll. And extended battery life lets you enjoy wireless freedom even longer.

Rating : - Wish the receiver was smaller
Great mouse expect for the rather larger snap in receiver. High quality stuff from Microsoft.
