I had heard that the Logitech more quality wasnt what it was. I confirm a bit. I had to return 2 times the keyboards before having received proper. 1 a touch strolled into the box because broken (the little plastic pegs was broken, impossible to recover the key). The 2nd received keyboard, the photovoltaic cell was removed from inside.
But once the 3rd received, nickel! Keyboard super nice, no problem recharging for now (this is 2-3 months I have). True, he quickly takes dust and fingerprints with this glossy black but it is really beautiful and a joy to use.
