Use: Use the keyboard a lot, sometimes also for games.
The first keyboard that I got sent, jammed the "Enter" key and the keyboard always leutete only after I raus the USB connector and have reingesteckt again. The exchange was not a problem, since in this regard no more problems.
Benefits:
The keyboard looks visually very good,
has with the touch panel special
and you can type very fast on it.
Disadvantages:
After less than half a year the buttons showed traces of wear: The color went by now one year instead of the "A" just a circle in the middle, like it is in some other keys. This must not happen for a year!
Conclusion: Not for people who the keyboard many benefits!
