I personally have a QPAD Mk-80 keyboard and their 5K laser mouse. The keyboard is really standard, it has mechanical Cherry Blue switches, just as many of Razer's keyboards. The mouse is what's special, as it has a five-finger grip rather than a four-finger one, and the optical sensor has really high DPI. I personally bought it for the grip, and I find it really comfortable. It's main drawback is that there's only two sensitivity modes (although they're fully customizable with both vertical and horizontal sensitivity).
