I have the Freestyle Edge, which is more or less the same keyboard.
The only complaint I have is that it's too large. The keys on the top left (esc) and right (backspace/delete) corners are too far. You'll have to move your hands to reach those buttons, unless you have gigantic yeti hands. A co-worker of mine who has the same board remapped the esc key to one of the macro buttons on the left to get around the issue.
Build quality is solid, the tenting kit works flawlessly. Custom software is to record macros, change lighting effects, remap keys is good enough.
