Initially, super, later deficient

First Impression:

Positives: Good looks (square shape, multimedia keys, blue glow from the logo), non-slip WASD keys (optional) and software to write macros.

negative: a non-slip key had one flaw.

Present impression:

Everything can be done by first impression. The negative part is the following supplements:

1.) The @ sign I can not do with "Ctrl" and "Alt". It can only be done with the "Alt" key.
2.) The blue glow from the logo is too bright and blinding me, especially in the dark. Even if the PC is off, it leuchtes further (silly if you fall asleep in the same room). There is no possibility of regulating the brightness.
3.) It is often happens that my character was going only to the right to play. This behavior occurs because apparently sometimes the "D" key continues to send signals, though that is not pressed. (Happens very rarely)
4.) The key with the number "1" from the "Num" key panel is not working.

The 4th point broke the camel's back for me. I'm going to get me a new keyboard!
Overall, I have the points 1,2,4 extremely disturbed (death criteria).
