This item looks very swish and windows vista installed it without the need for a driver disk. If you are not confident in the auto hibernate function to save batteries, it has an off switch underneath. If you want to take it on your travels for your laptop, it has a slot underneath for the USB receiver to be stored while not in use. The cursor travel speed is a little slow but that can be adjusted in the control panel mouse section. I am a gamer so set it to maximum. It also has two extra side buttons that can be assigned to other uses during game play. For the price I paid you can not go wrong. Because it was in bubble wrap and not in a box the postman could fit it through the letterbox.
