Batteries pure, receiver plug, and already it works perfectly on your PC. Super replacement for my old Logitech MX Air. Unlike the old, the Fly Mouse only be operated in the air, ie who wants to push a mouse normal, needs an additional device. So I did it, the interplay of the two mice in Windows 8 works without problems. What angekt the feel, I would find a roughened surface better. That's why only 4 stars. The mouse is smaller than expected, but is ergonomically in the hand. Design is also a bit cheap, mainly noticeable when the mouse is next to my other remotes. Right ugly, the green light is in operation, but that goes for happiness quickly out. Otherwise, absolutely no complaints about the processing, no creaking or rattling. Batteries, incidentally, were not there. I find ok if you anyway want to use batteries.
