The mouse works well under Windows 8.1, it will not require any drivers. In the beginning there was only a small problem, I had to Winodws in Device Manager prohibit the Bluetooth Adapter into hibernation to move. Otherwise Windows has the connection of all ~ 30min ended. So it works perfectly.
In terms of size, I find it quite enjoyable, although I usually use a greater Mäus (Logitech MX 518). Reminds me of my old Raptor Gaming M1 mouse, which was also slightly smaller. As notebook mouse they served their purpose in any case, as long-term use at the desktop, it is a bit too small for men's hands.
It is still included a plastic box for the mouse, quite handy if you're traveling a lot.
