After I was super happy with my mice and mouse pads Roccat, I decided to treat him as well a keyboard the same brand and - lo and behold - it corresponds perfectly to my expectations!
Although is quite a cabinet (of the dimensions here), but the supporting surface for the hands is very pleasant (even with longer time on the PC (12h +)). The resistance and the response to the keystroke in my opinion, very good, no accidental touch and still good "feedback".
The programmable buttons are quasi "necessary" so that a keyboard these days may not be designated as a gaming keyboard, be by myself but never used (can never remember that what is where is;)).
The only deduction: On my Windows 8.1 64bit the driver has made extreme problems at the beginning and then either Windows has given up the ghost, or the driver. Has dissolved the next Neuaufsetzen, no solution has the ready, in case anyone has the same problem. The support in this regard was unfortunately very economical and helpful in any way, on the other hand, it is probably difficult as a specific problem to "treat" ...?
Short Summary:
Pro:
+ Super comfortable (even for a long time no wrist pain or similar)
+ Good keystroke
+ Send Optics
Cons:
-Treiberproblem / Lack of Support
All in all a great keyboard!
