I got this keyboard now (after only 2 days, compliment!) And am absolutely thrilled already what you get for your money here! The keyboard is very high quality, it shows the weight (1.6 kg proud!). The pressure points are soft but not flabby, just right for gaming. I particularly like the Dimmswitch for lighting. While the keyboard has only 3 colors, but I did anyway all the time that the red light on. Apart from that, one of the few keyboards that I know which illuminates not only the letter but also the gaps and even the sides (Looks like Unterbodenbeleuchtung, very cool!)
About the multimedia keys, all important functions can be controlled. Who does not rely on programmable keys, but claims to have a reasonable luminous keyboard for little money, can not do anything wrong devinitiv here. :) I have a Logitech G19, and quite honestly, this is currently really prefer me.
PS: The comment concerning lack of Kros I can not understand, I just used commands with 4 buttons simultaneously worked. :)
