Bought the version with Cherry Brown switches. Feels great to type on, responsive, clean action. Grips the desk well. It is sturdy and rigid. Not as heavy as a metal-cased keyboard.
Upgrading the firmware to the latest version was easy using the Cherry app and this fixed a problem where the Windows key (and Caps Lock, Num Lock keys) glowed too brightly, they are fine now.
The backlight function illuminates keys evenly, making the letters and symbols easy to see. My desk is in the corner of a room, not well lit, this keyboard is ideal, I type faster with fewer errors.
The brightness is controllable, 10 levels, from off to very bright (not sure who would use it at the highest level - but it's there if you want it). Also, it is possible to adjust the brightness at smaller increments in between the 10 steps.
I use the keyboard primarily for productivity, with occasional gaming. It has a useful feature, game mode, where it disables the keys that can interrupt a game (Windows Key, Alt-Tab, Alt-F4). When in game mode, those keys aren't even sent to the PC, so no chance of accidently ruining game play.
Would suit someone who wants to be or is fast on the keyboard.
