Summary: Upon initial setup of the mouse, I had to work out some kinks, but if you have the right computer I think this mouse works perfect. I see lots of people complaining that this mouse doesn't work the way it's suppose to.
Summary: After installing the DVD included software, turning on, and pressing the connect button this mouse was able to connect to both my laptop and desktop computers. No USB receiver is required. Computers must have built-in WiFi.
Summary: The design of this unit is excellent, but there are no drivers available that will permit it to work with Windows Operating Systems except Windows 7 and Windows 8. It is not compatible with Windows XP.
