Very good keyboard, the wrist pad is amazing, but the wheel for the sound broke down very quickly.

After 4 years with such a keyboard, all the buttons there at del, end, pgon, home, ins, pause, numlock and the ones above for the "videos" have broken... but also the up and down arrows. Basically, they haven't exactly broken, they've just "stuck" and are pressed constantly, which is very annoying. I disabled them through the app. Nothing has ever spilled on it and I take good care of it. It's a shame because it's a lot of money for such a keyboard. If it was 7 or 8 (euros/dollars), I'd say okay, but...

Definitely one of the best keyboards in terms of keys and RGB quality, it's superb as you also have a lot of flexibility with the ICUE software to create your own Custom Profiles.
Why 3 stars?
1 - The volume wheel after about ~1 year doesn't work properly.
2 - After 2-3 years of use, some keys have broken/burnt RGB LEDs.
3 - Price.

I waited a long time to write about this particular keyboard because I wanted to be sure about what I would say. Unfortunately, it is not worth the money, and it is not cheap. After more than 7-8 months of use, the wheel on the top left and the volume control key constantly stick to the point where they are now useless, and I cannot use them! The volume goes from 08 to 100 just by touching the key! I have replaced the sound knob with an external one from AJAZZ.

Also, the wrist rest has frayed and will soon be useless too, which means the keyboard will be useless for me due to its height!

The software has bugs and is cumbersome compared to others I have tried. It crashes frequently on different computers for no reason.

The keys are OK, and cleaning them is quite easy. The lighting is intense, although I haven't really used it at 100%. I probably just need the keyboard to be illuminated to see sometimes in the dark.

Overall, I would not recommend it!

After 10 years, I decided to buy a GOOD keyboard. I was torn between Razer and Corsair. My choice did not disappoint me at all! After 1 week in my possession, I would describe it in one word as 'Excellent'! Beautiful and heavy construction, very good material quality, Full RGB (yes, I have completely fallen in love with RGB!), very fast key response, plenty of settings via iCUE! The cushion... won me over instantly! Very convenient and quality leather! Purchased at €200, which I believe is just about worth its price! I wouldn't pay more. I highly recommend it. So far, I am very satisfied!

Owner of 3 Razer keyboards for the last 7 years. After many defective Razer products, I decided to go for something Premium and obviously change companies. Very high-quality keyboard, however not worthy of the 269 euros it is currently sold for. I bought it in July 2024 for 203 euros. At 190, at most 200 euros, it is barely worth it.

The wrist rest that Razer charges 30 euros for is now included, so we are talking about a keyboard worth 170 euros.

The feel and sound cannot be compared to any other I have had in the past. Slightly noisy, NO COMPARISON to the Razer Green (Clicky) switches. You can easily play or work while someone sleeps 3 meters away in the room.

Dual USB Type-A for powering the LEDs and transmitting information to the motherboard. Thick premium cable that resembles the thickness of a 20 euro Display Port cable that I use.

Finally, 0 input lag at 8,000Hz tested in PUBG as well as several offline games like Hogwarts Legacy, Assassin's Creed, Ghost of Tsushima, etc.

It has a very good key feel, the noise is moderate, meaning it doesn't make much noise and doesn't bother much, for someone who has an issue.
So many functions, through the program you can change all the buttons if you want and + the 6 additional buttons that you can make "bot" meaning with one button to make a combination of buttons, you can set frequent timers, everything.
It is beautiful, the feather pillow, the lighting strips, so smooth both on the keyboard and around it.
I have been using it for a year and I truly enjoy it just by looking at it

The best keyboard I have ever had. Very beautiful and with countless capabilities. A big plus is the detachable wrist rest. The only negative is that it requires 2 USB ports to function, which is not enough to make me take away a star from it.

The keyboard is aimed at professionals who can take advantage of the 0.125 response at 8,000Hz, which is why it costs so much. Amazing for me personally, as I have high demands in COD due to my high rank.

Whatever we say is a little far from the best on the market so far icue has everything macro synchronization rgb and many more but it was really what was missing from my setup... if you have the money, it is definitely your choice.!!! Former owner of Logitech 910 and other companies much better than all the Corsair k100 of course what you pay for you get the law of the market now if we pay more than we should it's another story

In technical specifications, it is the best, the one and only downside is that the keys are not on the same level but higher up, which makes it difficult for me to work with. Having the entire keyboard in one piece is good, but having the keys on different levels is completely uncomfortable.

Very good keyboard. Fully satisfied even though its price is a bit high. If you have the means, you should get it.

It has unlimited possibilities for reprogramming the function of the keys. In each application, you can have a profile that activates and changes the function of each key with combinations of macros, etc. This is the main reason I bought it, apart from the other features it has. This makes it very useful not only for gamers but also for programmers, designers who work with development environments with many shortcuts

Generally, I am satisfied so far with the use of the K100. It is my first contact with a Corsair product for personal use. It is customizable in terms of macros and lighting. The wrist rest is very helpful in supporting the wrists when using the keyboard for many hours. I speak from experience as I have tested it during a 3-hour gaming session.

I won't say anything positive, others have said it all, the keyboard is a gem... the only negative thing is its price, if you can afford it, you should get it without hesitation!

Is it expensive? Yes.... Does it bring you joy? Yes.... Amazing feeling on the keys, not tiring at all when typing.. I have nothing else to add!

Okay, words are unnecessary! What you give, you get! Incredible quality! And the switches are silent and responsive! It's worth every euro! If you have the money, buy it with closed eyes, don't hesitate!!
Update 6-2-24: I haven't regretted a minute since I bought it, I have loved it! It hasn't had the slightest issue after endless hours of gaming!!

Having come from Corsair strafe rgb, I will say that it simply worths every cent, great variety of settings in lighting, macro keys programmable on the wheel you assign whatever function you want, immediate response without any delay. I highly recommend it.

Well, I decided to make the switch from Razer Huntsman Elite since I've had it for 2 years and I wanted a change. The keyboard is perfect in every aspect... although I didn't expect to see a difference in terms of speed compared to the Huntsman. And yet, I did notice a difference.
The lighting is awesome.
The responsiveness is amazing.
The build and appearance are perfect.
And it's quieter compared to the Huntsman.
