No complaints about the product, but the price is too high.

Finally this keyboard is fairly standard but does everything well: fine, design, wireless, easy to recharge (battery and not batteries, which are recharged by plugging the keyboard directly through USB), silent keys, ease and speed of installation (not always the case for Logitech), backlit keys with presence detection (even if this detection is not 100% reliable), convenient typing, no big fault to be attributed to him (just as some small absence of light key to "num lock", a wrist rest shallow black messy), if not its price range.

For that price there were large in terms of racing beasts gamer keyboard, with plétore softkeys, responsiveness foolproof etc ... So I feel that here Logitech has clearly misled price range. Maybe he will go down over time, for 50-60 it would really be perfect without the wireless keyboard. But meanwhile, it is not worth 5 stars as it is for me, too bad.

Back after 2 years of use: Logitech keyboards are definitely not made to last. This is the 2nd Logitech keyboard I own slamming after 2 years of activity. Finally it is not "dead", but in, rechargeable battery stopped working and after change is the third key that presented a problem. There is not, contrary to mice of the same brand, location on the keyboard to store the tiny transmitter that users lose very easily (and Logitech bill at full price, 20, while you can have supplied with a wireless mouse for the price ...). In short why he lost his fourth star.
