That with the illumination is perfectly true, you can see the illumination only when direct draufschauen fully.
For people who do not know where the keys are in the dark and the keys have to look for the Adler principle, this keyboard is completely inappropriate;)
The pity is that the multimedia keys are not illuminated, but not a must. If you have used them a few times, you know where which keys are.
What you have to say that is you do not feel very valuable. It has often been the suspicion that it is very cheap plastic. Otherwise I can not express it. But you met your good purpose and work well otherwise wonderful. The palm rest is also more than practical. The keystroke is a bit louder than expected, but tolerable.
I for one can issue a buy recommendation for gamers. For the average consumer, a backlit keyboard with macros is anyway only gimmick.
