This mouse is small and compact with good wireless performance and tracking on many surfaces. the wireless receiver also stores inside the mouse for portability. A few qualms keep this mouse from being perfect, but it is a good option for mobile workers. The wireless receiver slips into a dock on the bottom of the mouse for storage and when you dock the receiver it turns the mouse off so no battery power is used. Power is provided by a pair of AA batteries with a claimed life span of up to one year
