Not only does the Microsoft Sculpt Mobile Mouse fit comfortably in your hand, but it fits with your mobile lifestyle too. Use it just about anywhere, even on a rough park bench or your living room carpet, because its revolutionary BlueTrack Technology works on practically any surface. Plus, it'll stay comfortable for hours thanks to its ambidextrous design that can be used in either hand. But, not only is it comfortable, it's convenient too. The mouse includes an integrated Windows Button that brings you back to the start screen with just a click, plus it has a 4-way scroll wheel that lets you scroll left, right, up, or down. Now, you'll be able to navigate webpages or long documents with ease!
