The Wireless Mobile Mouse from V7 is pocket-sized: making it ideal for On-The-Go users. The mouse features a precise optical sensor for smooth tracking, as well as adjustable dpi settings for even greater control. The 2.4Ghz Wireless dongle stores in the bottom of the mouse and the mouse comes with a AA battery, so it's ready to use right out of the box. The Mobile Mouse is ambidextrous by design and is comfortable for either hand, plus it's backed by the V7 2-Year warranty.
