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. Corsair support has been helpful in amending the problems, but my second replacement had at turnaround of two months. I received that replacement middle of November 2014. As of Jan 2, 2015, I have reported more dead LEDs.
Summary: Badass keyboard been using for a year now mostly with no hiccups except when I try to mess with the software. one led gave out already but I hardly even use the illuminated keys so its not a big deal to me. I use this keyboard strictly for work as I don't game. I use it mostly for Photoshop and illustrator and the macros are a great addition and i use them everyday.
Summary: Being one of Corsair's flagship keyboards, I found it slightly disappointing. Unboxing the keyboard, I was quick to notice the sturdiness and weight of it. The overall feel gave me a sense that it was built well. My first impression was that I certainly wasn't a fan of the MX Red switches. MX Reds seem to be one of the most popular offerings among keyboards out there, so I thought they must be the best.
Summary: Pros: Too many to list, so I'll just say every function on the keyboard works as described. Cons: I've had the keyboard for three months and two LEDs have already died. The keyboard also has random fits, as if all of the keys are being held down at once, and it will not stop until I unplug it and plug it back in.
Summary: This is a gorgeous keyboard that is simply a joy to type on. I've never had so many people compliment a keyboard before. It's that good-looking. I love the way it types and sounds. I had never been so happy with a keyboard, but - The problem is the LEDs. At first, the number 3 LED went out. Then Caps Lock... Then Shift... Then R... Then 3 on the Num Pad... You can see where this is going. My LEDs are dropping like flies.
Summary: The keyboard could have been great but for two big flaws. The first is one that many have complained about. LED death. I am an engineer and suspect that they are pushing the limit on the LED specs. If you pull the key cap off and look at the light (even at the lowest setting) its very bright. I bought this key board in May and in Nov there are 27 bad LEDS. I would do a warranty thing but since I suspect this is a basic design flaw there is no point.
Summary: PROS: Looks nice, I love the volume roller. CONS: -The LED's burn out without reason. Even on unused keys that aren't illuminated! I had my G keys not illuminated, just turned them on and a few are out. I bought this this year and already 26 keys are dead. !!! 26 LED's Burnt out!!! and to have them fixed I would have to pay 30$ shipping. -The software is garbage, and G keys can't be used for key combinations, had I known this I probably wouldn't have bought it.
Summary: Keyboard is fine. The LEDs are crap, though. I noticed right away four of my keys (F1, F4, F6, F9) are not lit. No big deal, as I don't really use them all that much. A week later I notice another LED no longer working (comma key). JUST NOW noticed my G6 key is no longer lit up. At this rate, my keyboard will no longer be lit in two months. Not worth sending it back. When it comes time to replace, ill stick with Saitek.
Excerpt: Bought this keyboard to replace an aging Microsoft 6000 wireless. Product is well built from quality materials. The tactile experience when typing is excellent. Installation with the supplied firmware and software was problem free. The problem started when I tried to attach the keyboard to my IOGEAR KVM switch. The keyboard was totally unresponsive and would not be recognized by the KVM switch. I contacted Corsair and they admitted that the KVM switch was a known issue.
Summary: I love this keyboard, I really do but the lights might as well be on a timer. This is actually my second one, my first one went out two weeks after it arrived, it would flicker all the lights and continuously enter the qwertyuiop\ keys as if they were being pressed. The second which I am using to write this review is now flickering the 3 and j keys. I have the extended care plans from amazon and I will wait a little longer before I send them in.
