+ Very light & compact (perfect for an evening on the couch)
+ For gaming (even without numpad)
+ Good reception quality
+ Fairly quiet (especially compared to my old Logitech)
+ Receiver was detected quickly and easily on both Windows 7 and Linux
half a point I would have to pull off because
a) no batteries are included
and
b) the supplied receiver is not compatible with the right mouse anchor, so you need to anchor both devices each have their own Empfänger..bissel cumbersome - a Unifying receiver would have been great.
All in all: good keyboard.
