Summary: Unfortunately I am outside of my 2-year warranty window otherwise I would send this guy into to be fixed. Instead I am going to purchase a new, non-Corsair keyboard as I feel a bit burned by this one.
Pros: Great feel and look the keyboard, easy to clean and feels extremely sturdy.
Cons: The back lights are going out like crazy. Its not even keys that I used often, its just completely random. About 50% of my keys are no longer lit.
Summary: I cannot recommend this keyboard in good faith because of the severe lack of quality in the backlighting. I am very disappointed in COrsair for both the build quality and support I received, and I wish I had never sold my K90 because it was superior to this version in my opinion.
Pros: I really like the idea behind this keyboard. A mechanical keyboard with 18 programmable macro keys is incredibly useful in gaming. The aluminum construction makes it feel very sturdy.
Cons: The backlighting on this keyboard is not built to last. I had to send one in for several issues early on, including some keys whose backlights had died within only a couple months. I have had the replacement I received for over two years, and no less than 8 of the keys no longer have functioning ...
Pros: The feel of the keys are just so nice along with the response time! It's like I can't live without this keyboard but, it has become a love/hate relationship!
Cons: Oh the LED's on this board just are not up to snuff. W A S D aren't burnt out and those are the ones I use a lot. This is the second one after an RMA for the same thing and I don't know if I want to start it again. Even if I qualify for one. It sure is a big disappointment for a longtime Corsair ...
Summary: This keyboard has a solid feel and great response from the keys. My only complaint are that the LEDs keep burning out. I'm up to seven dead LEDs, under minimal use (this was originally intended as a gaming keyboard, but life seemed to get in the way of those plans).
Summary: The keyboard looks great, the LEDs are nice and bright (until they start burning out). This is a major problem with the white-LED K95s, If you are bent on getting this keyboard for some reason, you'd be better off buying it in-store locally, and springing for the IPR; it'll save you hassle and...
Pros: Nice design; looks and feels great
Cons: LEDs burn out really quickly; have to ship back to Corsair for a fix. Software is absolutely terrible; it has less functionality than the SW for my 9-year old Logitech G11
Summary: This may be a little nit picky so take it with a grain of salt. The caps lock button is way to close to the "A" button in my opinion. I am constantly hitting it when I am typing. Of course it doesn't help that I have big fingers, but I never had this issue with other keyboards
Pros: Nice Looking Keyboard
Cons: So I have had this keyboard just over 2 years now. It still functions properly, but I don't think it's as responsive as when I first bought it. At 1st it did not bother me that the LED lights were burning out, but now over half the LED lights are out. It makes me angry that I spent so much money ...
Summary: I used it incredibly lightly. I work every day from 10 to 8, meaning on average I only use it for 2-3 hours per day at night. For it to have had all those LED failures with such usage- I am extremely disappointed.
Pros: - Action feels decent. - LEDs were nice for the first few weeks.
Cons: - Huge - Keys seem oddly "tall", I had little clearance between the keyboard and my desk. - LED failures. I had this keyboard for three weeks before the first LED failed, after that they stopped working one by one until I replaced it, after about six burnt out.
Summary: Stepping up from a standard membrane keyboard, this mechanical keyboard is a pleasure to use. That's where it ends. I'm currently about to send in my 3rd keyboard in less than a year after my purchase for dead LEDs.
