Summary: First of all, it's a great keyboard except for the few rubber keys they added to the mix. Support is also great. But, you might be talking to support quite often. Just log in to their support forums and/ or google K90 "stuck keys" or "dead". When I had first received the keyboard,I had faced the "stuck keys" issue. Specifically, a random key press would get stuck until you press another key.
Summary: Really loved this keyboard, so kudos to the design team. I was not impressed at all by the software, the macro functions weren't as extensive as I would have imagined them. (Fairly simple actually) Pros: -Mechanical keys are fantastic -Backlight is excellent and good looking -Brushed metal was superb, felt great and looked great -Never really got dirty, the way the keyboard was designed really repels dirt and it's very easy to clean -Excellent feel to the keys with super...
Summary: Pros: -Most of the keys are extremely sensitive so your keystrokes to through very fast. I suppose this is why they say it's good for gaming. I definitely got used to typing a lot lighter while I had it and the louder key presses made me feel like I was typing a lot faster. -It's very shiny. Really like the aluminum! This was the main reason I bought it... =P It gets an extra star because it's very pretty. Cons: -Mine was defective.
Summary: I purchased this keyboard from Amazon about 3 weeks ago and was immediately disappointed for the following reasons: 1) 5 broken LED's It's very clear that these keyboards go through zero QA before being shipped. Many other users have received this keyboard with broken LEDs, so it's a real problem. 2) Multiple crooked keys Many of the keys came crooked/titled. Once again, it's very clear that these keyboards go through no QA before being shipped.
Summary: I wanted to try the new K90 from Corsair since it is a mechanical keyboard, which I love. However, this model left me very unimpressed due to the overall design. Let me state this has nothing to do with the "Red" style MX switches. It has to do mainly with how this keyboard was laid out. The Corsair K90 has what they call a "floating" style key that is designed to raise the key itself from the board.
Summary: I ordered this along with Corsair's M60 mouse. I at least got this to work, which is more than I can say about the mouse. I ordered this to replace a Logitech G110. My initial impressions of the K90 were favorable. It's very heavy and a beautiful piece of hardware. The software seemed to be pretty hit and miss. There was no form of help or instructions to be found within the software or documentation.
Good Keyboard, Bad software, even Worse Customer support. You will just have to get used to that DEAD LED on nearly Every K90!

Summary: First off this is a Great "Gaming Only" Keyboard, and this should be 4-5 star review, but to my misfortune I had to deal with Corsair Tech support! :( So like I said for gaming it doesn't get any better then this, Typing on the other had is not so great. The macro buttons G1-G18 are nice, to bad there not in a great place, and that they use rubber dome switches.
Summary: I really wanted a backlit, mechanical keyboard with media controls, which doesn't leave many options. I enjoy the feel of the keys, and the look of the keyboard is nice, although the media keys are inset too low. They are surrounded by the seemingly tall number pad keys and are not easy to access. I do like the volume roller and the mute button. They are a nice touch. I also like the Windows key lock for gaming. The keys that aren't mechanical don't really bother me.
Summary: I've never reviewed a product on Amazon before but seeing as I have just completed my second RMA for this product I thought it was about time I did. The problem with the first keyboard I received was that several of the LEDs on the back lit keys stopped working after a few hours of use (not days, hours!).
Summary: Edit: Below is my original review, and it's really positive. Abrubtly however, the keyboard died on me. It took a few days, but began with the PC becoming stuck in a boot-up loop. This was followed with a day of USB disconnection warnings. Finally, the K90 started to fizzle out, with the lights flickering and slowly dimming. Now it's completely dead. Ive tested it on my other PCs and laptops, it's remained inoperable.
