Summary: its a nice keyboard for general use. Game button to keep the windows key away from your gaming session. My biggest problem should be a full size keyboard instead of keeping the key the same size the squished everything on it by 1/4in for the gaming keys. Really there was no need to do that at all.
Summary: Overall a good keyboard. The keys are responsive, construction feels good and the layout is familiar. The negatives for this are that the keys can be hard to read during the daytime as the letters are back-lit. More annoying than that is that the rear legs to raise the back of the keyboard are A)reversed, so they fold-in to stand up and B) they are short. They only raise the back by 1/2" unlike most of the keyboards that raise the back by 3/4"-1".
Pros: The software which has to be downloaded is user friendly.
Cons: The overview is somewhat misleading. The back-lit keys fade when viewed at an angle. The grey gaming keys which are not back-lit are hard to see in the dark. You have to press the function keys to get to volume, mute etc. The keys are very close together and might pose a problem for someone with large hands.
Summary: I thought, hey! flashy green lights and some grey keycaps! Sure, it has a Call of Duty logo, but it's cheap, I can just scratch the logo off. Well it doesn't scratch off unless you spend 5+ hours working at it, and even then it doesn't look good as you can see the adhesive used. The lights aren't anything special, and aren't as cool looking as you would expect some lights to be, though they do a good job showing the keys in the dark.
Summary: Bought to use for gaming as some keys on my Logitech illuminated keyboard gave out. Keys not as tight or quiet as the Logitech illuminated keyboard. So I also replaced my Logitech illuminated keyboard for normal use. Also the keyboard slides all over the desk when gaming. Only has 2 rubber feet everything else on the bottom is hard plastic.
Summary: I caught this keyboard on sale but I would not recommend purchasing it at any other time. The keys do light up but they are not very bright, even on the highest light setting. I would have liked some music player hot keys (volume, play, etc.). It is fairly comfortable to type and the keys are responsive though. Overall not bad.
