Okay, I got this so I could see the keyboard at night. No other reason, and it does not disappoint. Connected perfectly, colors show up clearly, all good. Only 'complaint' is I think all keyboards need a discreet off-switch. You've got kids? You need an off-switch. My 4 year old is getting great running macros on this board, so I guess that feature works well too.
I've been using Steelseries keyboards for a long time. Was hesitant to try the Corsair. Am very happy. Took a week to get fingers used to the macro buttons but OMG are they handy. Will be replacing like for like in the future.
