Summary: "Caps Lock" key is not lower on the right side next to the 'A' key (unlike all keyboards designed since the 1500's) which of course means that when hitting the 'A' key, you often hit the Caps Lock Key.
Pros: Lots backlit color choices and 5 separate color profile choices to switch between, no clicky noise (what is the obsession with people who want keyboards that sound like old typewriters?), key travel is not far so easier to type on.
Cons: Paint wears off keys. Only had this keyboard for 4 months under moderate non-gaming use and the paint is wearing off the 'A' key. Instead of seeing the letter 'A', I see a black key with the LED color where the 'A' is supposed to be.
