Summary: As many others have said, the LEDs on this keyboard die. I've lost 15 on mine, and it is less than a week out of warranty. The LEDS still light up, but very dimly to the point you have to be in a very dark room to notice, and only then with the keycaps off. For a premium keyboard this is absolutely NOT satisfactory. Any help out there?
Summary: I bought this keyboard a few months ago in Feb. 2014. It was a replacement for a Logitech G15 gaming keyboard I'd had nearly 4.5 years before it died (it did great for a $99 keyboard that sees extensive daily use!). I enjoyed that G15 immensely, and it had everything I needed, so I wanted a new keyboard with a lot of the same features.
Summary: This was so easy to set up and has worked great...then after just 6 weeks it is not responding to any keystrokes. The next day even the lights no longer came on, I have tried it on different pc's. I submitted a ticket on June 2nd, I got a email asking me to submit my receipt so I can rma it. I did this on the 3rd and have not had any response from Corsair in spite of each day opening my ticket and asking for a response.
Summary: Had this keyboard maybe a year now and every once in awhile it decides to stop typing. Unplug/replug several times and occasionally it will start typing again - maybe 20-30% of the time it never comes back. The computer does recognize the device removal / connection. So here's the catch... the keyboard bricks itself randomly. This keyboard has never been abused or had anything spilt on it.
Summary: Going to look in to see if Corsair will repair it since it's not even a year old. For the money I paid, I expect a keyboard to last a couple years before falling apart at least.
Pros: Everything I want in a keyboard
Cons: I've had this keyboard for nearly a year now, bought it on sale last summer. Recently I noticed that one of the LEDs has gone out, and just today a second one has. Both of the keys I rarely/never use but they are already going out. The buttons work fine but there is no backlighting behind them now. Very annoying since I have treated this keyboard very well and always transport it in the box it came in when I need to move my PC.
Summary: After years of gaming as well as using my PC for non-gaming purposes utilizing inexpensive, non-mechanical keyboards I finally caved-in and decided to spend some cash to get a good mechanical keyboard. I've long used Corsair products in my PC builds including most notably Corsair RAM, PSUs, and cooling solutions. After batting around a few different keyboard manufacturer brands including Logitech, Razr, Steelseries, and Corsair I settled on the K95.
Summary: After 2 months of casual use, 3 LEDs no longer turn on. And I can confirm it wasnt caused by use, as the lights were working one day, I turned on the computer the next morning and 3 had stopped. This is very distracting on a keyboard, to have some keys lit and other not. Ive started turning off the lights entirely, but without the backlight the letters are a very dull white, and having the backlight was a major reason for getting this keyboard. *Update* June 15 2014.
Summary: Firstly, this is a very very nice keyboard. The tactile feedback is excellent. I love the fact that you have 18 programmable keys. The 3 light levels are pretty good (i.e. brightest is good in the dark and the least brightest is good during the early evening). However I must state that I am extremely disappointed in the burn out rate of the LEDs. At present my 1, D, F, G and B keys no longer light up. I wish there was a way to change out the LEDs.
Summary: Pros Keyboard is designed well, Feels good Cons lights for the keys are starting to go out (9 key in counting) I'll see how costumer support responses and change my review accordingly =P Edit: 2 stars to 1 customer service for corsair sucks. the entire interface for RMA is terrible. for a guy that spend 2k plus on just ram products, and more on cases, PSUs, SSDs, this really blows... I hope you never have any problems with your corsair products.
