It's not my first keyboard from Logitech, otherwise I would never have ordered me on the Internet. But it is the worst of all. Okay, for the price you can not expect much one. Therefore, I have tolerated previous models that me sooner or later always cancel the adjustable feet and that the letters are no longer visible on the keyboard after one year continuous service. If then stuck the individual keys for two years, then you swap out the keyboard. But now that the keyboard, unlike the mouse, no contact will receive and therefore simply does not write (or not hinterherkommt writing), I've never had. Extremely annoying, extremely unnecessary. I advise on the purchase!
