I can not say much about this keyboard. Yes, it is really cheap and actually an OEM product, but it should at least keep more than a year. I got three of these keyboards in the past 5 months break. Only me killed in the first off the spacebar. She responded sometime simply no longer. The same game with the Enter key in the second. In the third I could not use the numeric keypad as the Num Lock probably stopped responding.
I hang quite a long day on the PC. I also tap a lot on the PC. Therefore, I now allowed myself a keyboard with mechanical individual keys. Never again such a cheap stuff. And more importantly: Never again something from Logitech! The quality was once again.
