With basically no setup, your mouse will be up and running. Just plug in the receiver to your USB port and start using it. Then configure the buttons as you like from your control panel, just as you would with any mouse.
The sheer tininess of this mouse and its portable design elements make it perfect for travel. It will easily fit into your laptop bag or a pocket, and the receiver conveniently snaps into the bottom of the mouse, conserving the battery and ensuring that you don't misplace the receiver, which is about the size of key fob. According to Microsoft, the receiver will sense your mouse up to three feet away, but in tests with a fresh battery, it still was fully functional at a distance of more than five feet. There's no recharging this pint-size pointer. It runs off of one AA battery which Microsoft claims can last up to three months (assuming you're careful about replacing the receiver when the mouse isn't in use).
