Summary: I had an old Logitech backlit keyboard for years and loved it. When it died, I wanted another another. I like you have 2 brightness settings as well as off for the back lights. The keyboard is okay, but I don't like the gray keys for the s-w-d-a.
Summary: The board itself is a good idea, but the buttons are way too tall, you have to press down too hard, the media keys kinda suck, hate having to press the Fn button everytime. Wish I could return it, but I've had it too long already.. oh well.
Summary: Build quality seems ok. Works with the software with my G930 headset. Good key;board except for one major flaw. The key labels. The backlight is very dim and lame. The writing/labels is ridiculously small Pathetic labels. I will have to get used to it I guess, because I like it otherwise. I take two stars off for the pathetic key labels and lighting.
Summary: I'm used to a very standard key layout, so the shift of keys to the right has been very difficult to get used to on this keyboard. I seem to be frequently hitting the function keys instead of Tab, Esc, and CTRL. The backlight could be even brighter and/or a different color. Red would definitely be preferred for night vision. Feel is okay, but this is certainly appropriately priced for the quality of keys.
Summary: Bought this keyboard, no for its gaming capabilities, but because of its illuminated keys. The problem is - the letters/numbers are relatively small compared to other keyboards. No a deal breaker, but disappointed.
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.
