Summary: This keyboard is amazing. I've never been let down by a Logitech product yet. I own a (all Logitech) G700s Mouse and love it, I own a pair of Z313 speakers and they've worked great for the 3 years I've owned them, I have this keyboard and love it, and I own a G35 7.1 surround sound headset (which I consider my best purchase of all time). This keyboard and the G700s mouse comes in a close tie for my second best purchase ever.
Summary: This is a great entry level keyboard for gamers. The back lighting works well and the keys feel responsive. I have used Logitech keyboards for a long time and have always had good luck with them. I would still be using my old G11 gaming keyboard from them but my daughter spilled ice tea all over it and I decided to switch over to using a wireless one for about a year.
Summary: For the price I would get this keyboard. Feels almost as good as mechanical keys, but not quite there.
Pros: Great Feel Keys feel a lot better than regular keyboard keys, almost as good as mechanical Backlight Keys are awsome and work really well Logitech Gaming Software that manages the macros keys functions is quite good
Cons: Macro Keys are a little small and I wish they were bigger
Summary: Was considering getting a mechanical keyboard but opted against due to noise; this one works like a charm! This item was on sale online but in-store they would not honor the sale. I literally had to order the item online for in-store pickup, do some other shopping while they moved it around the store for hours, and then pick it up. At that point they tried to give me the wrong keyboard!
Summary: My job requires me to copy and paste a lot of things and I noticed that this would get increasingly annoying as time went on. I discovered the magic of the macro keys and knew I'd need these in the office, so after some research I decided to try this keyboard as I wanted something inexpensive. I am now wishing I hadn't bought a steelseries keyboard for home because this is a fantastic keyboard! I'd love to have one for my home office.
Summary: I really like this keyboard. The "key feel" is very nice (smooth with pleasantly concave shapes to all the keys), and the backlighting looks good. You can set the G keys to various game macros or whatever - personally, I used them for hotkeys to open certain applications or for duplicate "home/end" keys on the other side of the keyboard and don't really mess with the various profiles for different games.
