Yes, put 80 euro (at the time of my purchase) in a wireless keyboard is a little painful. But it all. It is backlit (as soon as the hand approach, therefore economic), battery (autonomy hallucinating - approximately a week for intensive use word processing), recharges in two hours or close via a long enough extension cord . Switch, battery meter. I add a design very ... very nice (between that and the physical pleasure of keystrokes, I did not find this kind of remarkable details in a computer), and I, for my hand, the perfect keyboard. So it is sure that Euro 80 was not given, but this keyboard has everything I wanted (no batteries, rechargeable, light) and they are not numerous. Besides I already had a mouse in the same series and I know he does not let go of me so soon. Even for the price, I would do this purchase closed eyes (and earlier, if I had known what I was earning in comfort). to use, to the must, mouse MX Performance perfectly compatible on a single USB port
