I got the same a little while back. It's my daily driver now. I loved it out of the box, and even more so once I put red o-rings on it. Tomorrow during downtime at work, I'm going to pull the keys off my G80-11900LUMEU-2, move the o-rings over, and stick them on the Corsair. I must imagine it'll be fantastic. Nice keycaps. Deeper F and J instead of little bumps.
My one complaint is that key repeat doesn't work entirely in any of the polling rate settings except "BIOS". Mostly it does, except for backslash, which is a problem because I swapped backslash and backspace because I'm a spoiled HHKB ****. It works fine in "BIOS", but now the scroll lock light keeps flashing for some reason, so I painted over it.
