The keyboard itself is top: it's hard to slip little, the lockable keys are extremely useful to get rid of the annoying Windows keys and their default layout is simply a joy to behold. Unfortunately, where there is light, there is also shadow. In this case, the shadow of the user who is illuminated by the blue status LEDs. These are so extremely far too bright that I had to bring on tolerable luminosity this with two layers masking tape. If you sit in an otherwise completely dark room, this is slightly blue illuminated. That's way too much of a good thing! Yet a strange thing at the edge: so far every computer to which I used this keyboard longer, sometimes had problems with it, it can be seen at boot time. No LED lights up, no key press is registered. Only after a complete shut down your PC or after Neuanstecken the keyboard this is detected. This implies a massive high starting current, the demands this keyboard to the USB interface. Why she does this - no idea - maybe for the blue room lighting. The problem occurs felt definitely 10. Start and is independent from the computer (occurred in the meantime 3 PCs and a laptop, each newer design). Despite this problem, I would not have missed it.
