Summary: The mouse seems to work very well. Unfortunately, I had to test it on a Windows 7 computer, becayse it suppose to only be compatible with Windows 7. So make sure you have a Windows 7 computer. I would have reviewed it sooner, but I still unfortunately have a Windows Vista computer.
Summary: I am running Windows 8 RP and the mouse worked right out of the box. It does ask you for your Facebook account but you can just skip it, the reason it asks you is because there is a button on the mouse to upload photos (completely unnecessary, but like I said, just skip it).
Summary: This wireless mouse requires Windows 7 and a WIN7 certified WiFi network adaptor. I have Windows 7 Starter on my Asus netbook. As far as the network adaptor, I didn't have a clue about that, but apparently it's there. The mouse works on Wi-Fi, and does not tie up a USB port.
