Now unfortunately I have now (about 6 months after purchase) festellen that the keystroke of some keys has deteriorated significantly!
Anyway, I can see the keyboard still recommend it, because I have transported the keyboard a few times and so may have geleidet including the keys. This I had done but with my former keyboard (Logitech G15) and there I never konnt deterioration of the keystroke festellen ...
Addendum: After I get out of taking the keys with bad reiteration and have built with difficulty again, the keys reiteration was ok again. It seems that the slight internal plastic parts were separated from each other.
