Customers are saying

Customers are pleased with the K100 RGB keyboard's quality, customizable RGB lighting, and comfortable key feel, especially on the optical version. Many appreciate the included wrist rest and the keyboard's responsiveness during gaming. However, some find the software less than ideal and consider the price to be somewhat high. A few users also noted its larger size and sensitivity might not suit everyone.

    Worst keyboard ever - known bug destroys work

    Wow - $200 for a keyboard that Corsair knows has a bug that causes the keyboard to start typing randomly. There is a "macro recording function" that apparently turns itself on and captures all keystrokes. Then it randomly begins to replay the macro which starts putting all those keystrokes into whatever document you are work on. Tabs, deletions, additions, anything you typed while the macro was recording starts taking over. First time freaked me out and led to hours of researching before finding out Corsair knows about this and it requires resetting the keyboard. Second time just ticked me off as I am watching work product get destroyed but the altercations being made and I cant even google the reset instructions with the macro doing its thing. If I could give negative stars I would - never buying Corsair again.

    Love this keyboard but there is a bug in the macro software where sometimes randomly in game play it will start repeating the keys you’ve hit. Not a big deal? It is. My password was blurted publicly in a highly populated World of Warcraft server in Dalaran (crowded city). NOT GOOD.

    Keyboard looks great. I feel like this would be a great keyboard if I didn't get a dud. The keyboard randomly will type numbers or letters from previous typing, close browsers, and pretty much takes on a mind of it's own until you unplug it from the computer. plug it back in and its good to go. Very annoying to deal with and has messed my email up before. I tried to get a replacement with best buy, but the return period was 7 days. the keyboard issue wasn't discovered until 2 day after the 7 day return period. I purchased this keyboard on sale for $200. No matter how great the keyboard looks, or all the functions it has, it's not worth the money for the hassle and potential harm if you step away for a second. Not worth it in my opinion, just buy something cheaper.

      Hello,

      Return periods are never 7 days, please get with the store again for assistance with an exchange as this sounds as it's faulty from what you describe.

    Defective Firmware

    Really wanted to love this keyboard. Checks all the boxes for features, feels great, and looks great. Problem is, after recent firmware updates this keyboard has been broken. Every few hours or so the keyboard will freeze and you have to un-plug then re-plug into the computer to get it functioning again. I have also had trouble with "Phantom typing" where it stores keystrokes and starts randomly typing on the screen. You don't need to take my word for it (I might read review and think inexperienced user), search the Corsair forums and see how many people are having the same issues. This has been reported for over a month now and no fix is in sight from Corsair. Save your money and buy something else, I sure wish I had.

    Huge learning curve with the layout of the keyboard. It was hard to adjust my typing style to accomodate the extra keys on the left. Returned the product because it wasn't worth it to spend $200+ to have to make mistakes and play games uncomfortably. It would be a better investment to make your own keyboard or buy a Duck Keyboard.

    For a $230 keyboard, no matter how feature rich, the quality of the keys is gross. They're loud and have a weird feel to them that makes it a bit difficult to type. Also, the only reason I got it was because the K95 I got needed to be returned for defects. Can't say this is a purchase I'm comfortable making again.

    I really love this keyboard out of the box but after using it for a little while I was having issues with accidental key presses especially with playing fortnite and moving the wrong direction that I wanted to because my fingers were resting on a key that I didn't mean to press.

      Hi Stealthrelentless,

      Were you depressing the key unintentionally? The OPX switches are linear and actuate fast so they may be activating because you are resting your fingers on them. If you'd like recommendations for a different switch type that might be more suitable to your style, please feel free to reach out to our support team: support.corsair.com

    I had nothing but problems with this keyboard. Constantly disconnecting from my computer, prompting other components connected to my computer to restart as well. The palm rest always got in the way and the wire routing on the bottom sucks. The buttons would sometimes click infinitely. Sometimes I would have to unplug it from my PC and plug it back in because it wouldnt respond to anything. This has got to be the worst keyboard I have ever used. I returned it after using it for 6 months. Super glad i got the protection plan on it.

    My keys keep sticking pressed down… considering how expensive it is…. That’s really disappointing, I also hate where the G1-G5 keys are placed (that’s my issue) because I keep hitting G1 instead of ESC

    Keylogging and Disconnecting Issues

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    The issues many others have mentioned I have dealt with also. Keylogging incident made me think someone had hacked my computer. Randomly throughout the day the keyboard will reset and the last key pressed will be stuck repeating until you unplug the keyboard. I had to move which USB the keyboard was plugged into so I could quickly unplug it anytime the issue occurred. This is awful for gaming. As a longtime Razer user who swapped, I am less than impressed with Corsairs high end keyboard.

    Purchased this keyboard back in November 2022. nothing but issues, would randomly lock up at least 1x per day, and the only way to fix it is to un plug and re plug the keyboard. it would input the last key you typed. exchanged it, and the same thing happened with the other one. after checking corsair's forum, there's a ton of people having the same issues due to its bad firmware. What a waste of my time troubleshooting this, after spending $200+ on a keyboard.
