The keyboard keeps what the description promises. Very pleasant is the lighting; without the use would be very difficult because the key assignment without illumination appears gray. Some letters appear slightly weaker illuminated, which is perhaps the material used. But this is not disturbing. The keys are big enough even for elaborate hands. So overall a bit bulky, but very solid, device that, unlike competitors from Logitech, the umlauts ä, ö, ü and the letter ß contains (so really the German alphabet). Against them competing products from Cherry I have considerable reservations, because in previous corresponding purchases only glued (!) Keyboards proved little "use resistant". It remains to be seen whether this keyboard fulfills the expectations placed on them in the long run.
I am sorry to "rectify" my review. The keyboard is not as solid as it seemed. Now, after half a year has passed, the black paint / plastic dissolves the letter "e" from. The letter "e" is the most used letter in the German alphabet. So also this keyboard is "not worth the money"! Or at most a star !!!
