The appearance fits, especially pleasant: the switch from brightly-blue absorb'm diche Orange; I wanted to upgrade my darkened jobs in order to enter more effectively; this works: you can the keyboard really see good and great use in the semi-darkness; the really big catch: it "hooked" the quick stop: remain the keys hanging undlassen always when they are not directly strikes from the top, press down only against resistance; That does not work! I had bought 2 Tastauren, and that's both so; So: I have rejected them, they can now after 1 week not return Mher use; There are now nearly 2x 18 Euro in the closet; I am ruefully returned to the beleuchtetn Logitech Tastauren (unfortunately the cost almost 80 euros / piece, but they are easy tip-top!); pity for money
