Then, once the inserted batteries, you connect your mouse, you go to the Control Panel, add a device and voila, the mouse is functional.
Then I love the center button, touch. It's very nice not to have wheel, especially since we can sail from right to left (and not only up and down) which in Windows 8 is not luxury! I can finally feel like a fish in water in windows 8 interface with all those tiles and elsewhere elsewhere (in contacts, in the tiles and wherever it needs to go from right to left ).
I do not regret this mouse designed for W8 enjoyable.
