K100 AIR Wireless RGB Mechanical Gaming Keyboard - Ultra-Thin, Sub-1ms Slipstream, Low-Latency Bluetooth, Cherry MX Ultra Low Profile Keyswitches - NA Layout, QWERTY - Black

Very smooth, love the light touch typing feeling of Cherry MX Speed, extra keys and buttons and knobs, and fully programmable RGB. I have been using Corsair K95 Platinum with Cherry MX Speed for 7 years and I needed another RGB mechanical keyboard for another PC, so I opted for Cherry MX rather than OPX so I don't have to get acclimated to new type of keys and swapping between Cherry MX and OPX when I move between PCs. I'm sure that if I haven't used Cherry MX before, I would have chosen OPX. I also used Cherry MX Brown, but I prefer Speed once I got used it. Although pricey (especially compared to Corsair K95 at the time I bought it), I took advantage of a sale. I couldn't find any mechanical keyboard that comes close to this one in terms of functionality and quality and programmability, especially the six macro keys on the left side I can't do without (I also considered Corsair K70 but they don't have macro keys). This mechanical keyboard is such a delight for gaming, coding, typing, etc. I use this on a Mac and Linux. Linux has ckb-next driver, and its development version (newer than release version as of Nov 2025) also detects the top left scroll and can program RGB on it. I created my own custom RGB lighting by copying one of the animations and then changing all the configurations to my liking. I use the USB port to connect my wireless mouse dongle and it works perfectly even if routed through a USB hub with on/off switches, then a USB KVM switch, and then through a third USB hub that is externally powered. If you are using a USB switch with mouse/key roaming feature that only works with a standard keyboard, there is a way to change the keyboard mode into BIOS mode by pressing some keys (search the Internet since it's not mentioned in the manual). You'll have to connect the mouse directly to the USB switch instead of the keyboard. You can revert back to normal mode with full functionality using some other key presses if you no longer need to be limited by a USB switch with key/mouse roaming feature. The wrist rest is very comfortable. It's nice that it's magnetically attached. The one in my old Corsair K95 had the plastic tabs broken so I had to throw it away. You probably won't find any alternative that comes close with macro keys, full custom RGB lighting, good quality, and the smoothness of a linear mechanical keyboard. If you've never used linear short activation switches, it may take some time to get used to it, but once you master it, you won't want to use any other switches. YMMV though.

I replaced my Corsair K70 RGB (the OG one) with the K100 Air. Ever since I started working from home- i.e. using multiple computers throughout the day- I've been wanting a better keyboard. My old, wired (with GIGANTIC dual USB cables) K70RGB had fantastic feel and features. But I wanted to move it around more than the cables would allow. Also a somewhat less gargantuan footprint would be appreciated; I still need the 10-key though. Enter the K100 Air. - Still mechanical keys (more on this later) - Wireless = more mobile - RGB, G-keys (macros), 2.4Ghz or Bluetooth (or single USB wired) SO- I went for it on Day One, despite the *astronomical* price (nearly $300). • The K100 Air has made my life easier. I can now use my own PC much more easily; I'm typing this on it now. Moving the keyboard has also given me much more mousing room on the desk. (I use another computer for work, with 2 monitors; it's to the right of my main PC (also with 2 monitors). It recharges via USB-C; when it's low on battery the lighting turns red. Or you can check in iCue and it shows the battery % charge. iCue also works fine for applying lighting- be sure you have version: 4.29.203 or newer, otherwise it won't recognize the keyboard. If you just see the wireless dongle in iCue but not the keyboard, update your software. • For the feel and 'mechanical' keys: it feels like the best laptop keyboard ever, but it does NOT feel like the mechanical Cherry switches you get on gaming keyboards. The keys feel very solid and predictable, but they aren't at the same level as Corsair/Razer/Logitech mechanical keyboards. I will say, the Corsair's keys are better than the (somewhat) low-profile keys on the Logitech G line (715, 915 etc). The Logitech ones feel (and sound) more springy, which isn't that great for typing. (or gaming) • As far as build quality, this thing does look and feel like an expensive item. It's metal on top, I believe plastic on the bottom. The lighting shows through the keys very well, but it doesn't shine out from under the keys like a full-sized gaming keyboard. It has a spot to store the dongle when it's plugged in. I've only used it via 2.4Ghz wireless, and it has been flawless as far as connection. You can plug the dongle into the back of a nearby PC directly and no connection problems. Also no interference with multiple keyboards and mice also on 2.4Ghz. The RGB lighting is adjustable from the keyboard, independent of the software. Brightness and lighting patterns (pre-saved onto the keyboard via iCue) are controllable without software. There's also a charge light, so you'll see it blinking and/or changing color when power is low. The iCue software also puts up an alert when it needs a recharge, this happens before the lighting turns red. Works well. I have to charge it about 1.5 times per week, with the computer on 24/7 and asleep for about half that time. • One thing about waking up from sleep: the keyboard takes about 4 to 5 seconds to wake up. In the time you press the first key to when the lighting comes on, the keys still work and are read by the PC, but it's disconcerting to be typing on a black keyboard. It does wake up fine, the lighting is just a bit slow. • Now, the key (ha) question: is it worth the money? As far as I can tell, this is the best low-profile wireless gaming keyboard available. It has many nice touches, gives me more features than I can use, and beats the competition in both the hardware and usability. Yes- it's really expensive. But for something that is your main interface to a system you use constantly, it is probably worth paying the premium. If I hadn't already got a Logitech for my work PC, I would get another one of these. That probably tells you everything you need to know.

I've owned tons of Corsair's previous keyboards starting with their early monocolor white led k95 to the various other iterations of the K70 and K95 that were released over the years. I've always had some issue with them that made me hope that it would be fixed. The first K95 had problems with the black on the keycaps wearing off and the led lights dying quickly. Later RGB versions seemed to fix the LEDs dying, but introduced issues with a single key press registering multiple keystrokes. Then the quality of the keycaps of newer releases seemingly degraded and were completely loose out of the box. So loose that if you tapped a key too quickly, the keycap would fly off the board. That got old very quickly. Then the K95 RGB Platinum also had the issue of some of the LEDs starting to become really dim compared to the other keys. I switched to the EVGA Z20 after I got fed up with the various issues, but found it had its own host of problems including random disconnecting from the computer and losing power regardless of what USB port I plugged it into. I discovered that Corsair had a new keyboard with a new type of optical switches and decided to give their keyboards one more chance. After some months of use, I have to say this keyboard is fantastic so far and all my previous issues with their keyboards appear to be gone. - The keys feel just right when typing. - The fonts used on the keyboard look a lot better and the keyboard overall has a classier look to it. - The keycaps are not loose in the slightest. They are snugly fitted to the switches and actually takes a bit of effort to pull them off so I'm not worrying about them flying off the keyboard anymore mid-game or while chatting. - There hasn't been a single instance of a single keypress registering multiple keystrokes. So far, the LEDs for these OPX switches have been holding up over the months and I hope they stay that way. - The keycaps are double shot so I don't have to worry about the paint on the keys coming off. - Not really a past issue per se, but perhaps due to the new OPX switches, it's not as loud when the keys bottom out while typing compared to the Cherry MX switches. An improvement in my opinion, but some people might prefer the louder clickety clack of the Cherry MX switches. As an added bonus, the wrist rest is also their best yet. It must use a memory foam inside as it has yet to flatten out even after applying a lot of pressure on like resting my elbows on it frequently. It's a huge improvement over the hard plastic wrist rests with the rubberized coating. It also conveniently snaps right onto the keyboard with magnets. If I were to list any cons, they would be: - Price. This is one expensive keyboard. I have had no issues with it so far, so I'll take it over having a cheaper keyboard with problems. - Easy to accidentally press a key if you're not careful as they are linear and don't require a whole lot of force. Also, they have a VERY short actuation distance. - I find the scroll wheel to only be mildly useful, but that's just my based on my own needs and usage.

TL;DR - 10/10. Premium price, but premium quality in return. I will admit that I was a little hesitant about getting a wireless keyboard, mostly because of battery life and dropped connections. My job sometimes requires me to act quickly to fix an issue, and I was worried about the connection suddenly dropping when I was racing against the clock. I had a Corsair K70 and loved it, but it was getting old and had started acting up on me so I thought I would take a shot on this one. Oh boy, am I impressed. The keys feel incredible, the battery life is fantastic, and the connection is solid with no noticeable input delay. The "Slipstream" wireless receiver can pair multiple Corsair products as well, so you don't need to take up multiple ports if you like their product line. Pros: - Battery lasts me several days, working 8 hours a day and typically gaming or browsing for a few hours on top of that. I usually leave the RGB lighting on the highest brightness, so you could get even more life out of a single charge if you turn it down/off. I haven't checked charge time from 0-100%, but it charges fast enough that it doesn't matter to me personally. - The connection is solid. I'm about 10 feet from the dongle with my body, desk, and other equipment in between and have no noticeable input delay or dropped inputs. - The feel of the keys is amazing. I know this is more of a subjective matter, but I think they have just the right amount of "click" and feedback. They're a little less "clicky" than the Cherry MX Red switches that were in my K70, but still tactile enough to feel just right. - If you're also using a Corsair wireless mouse or headset, they can all pair with a single "Slipsteam" dongle so you're not taking up multiple USB ports with different receivers. I imagine this also cuts down on the interference that would be caused my having multiple wireless receivers next to each other? - Multiple connection modes - wireless, wired (while charging), and bluetooth with up to 3 pairings. Switching between connection modes is as easy as pressing FN+[corrosponding key]. - Premium quality in every category that I can think of. Cons: - If you don't already have/use it, you'll need the Corsair iCue software to control many functions of the keyboard. I don't like having so many different pieces of software to control my system, but it's practically unavoidable. Luckily, iCue isn't one of those "in your face" pieces of software. It runs at startup without any popup or loading screen, and simply sits in your system tray until you need it. - Expensive, but you honestly get what you pay for. - That's it. I have no actual complaints, I love this thing.

UPDATED 2022-11-17: After using the keyboard for a few days, I'd say this is a pretty good keyboard. I do not have any data on battery usage yet. The keyboard lighting effects are very nice and highly customizable. This being said the keyboard has a few areas for improvement: - unlike the other keys, the volume control wheel does not keep the keyboard alive. So if you watch youtube videos for 15 minutes using only the mouse and the volume wheel, at some point the keyboard will go to sleep mode, and the volume wheel will stop working completely (until you press another key to wake up the keyboard). - it does not seem to be possible to assign a key to launch an application (say the Windows calculator) using the "Hardware Key Assignments". This is possible using "Key Assignments" but this won't work if you use an A/B switch and your alternate computer is not running the iCUE software (unlike lighting effects which work in "Hardware lighting" mode). My old Logitech Wireless Solar Keyboard K750 could launch the Windows calculator from anywhere. - one major design issue which I initially thought was a bug: if you save your lighting profiles using the iCUE software to the keyboard slots, it works but only as long as your keyboard is connected to the same computer. If you use an A/B switch to toggle to a different computer, the keyboard does not retain its settings on that other computer. This is because the iCUE software is using different profiles if the keyboard is connected wirelessly or with the USB cable, but you cannot copy the wired profiles onto the wireless profiles. You have to recreate them one by one. Not a bug, but a major usability issue especially because the "Lighting library" is also not sharable between the wired profiles and the wireless profiles! - also if you use an A/B switch to toggle between two different computers, there is some lag for the keyboard to switch over (longer than what I had with my previous keyboard). - macro replaying seems to be real time. So if you pause while recording the macro it will also replay the macro at the exact same slow speed. This may be good for games where timing is everything but not so much for software development. This is probably by design but it would be nice if this was configurable. Also, you have to be very careful about macro recording (don't do what I did by mistake to assign a macro to the Windows key, because the Windows lock key is also used to record macros!) - Keys are a little noisy (compared to a keyboard like the Logitech Wireless Solar Keyboard K750) - The Shift keys are represented with an arrow pointing up to access characters showing at the bottom of the keys. This is unlike most keyboards and can be confusing. Design blunder? - it is not clear if the on-board battery is replaceable, possibly reducing the keyboard longevity. The keyboard appears to be locked sealed, without any screws. - Keyboard itself is entirely black. Style would greatly benefit to have a little white rim all around, similar to the Logitech Wireless Solar Keyboard K750. In a minor note: - Product manual is downloadable via a QR code, but who has a QR code reader on a computer? - iCue software is 1.1GB to download - the predefined quick lighting zones in the iCue software are lacking. You have to create them (e.g, "Function keys", "Numeric keypad", etc...). - it would be nice if the keyboard could switch profile automatically based on the time of the day (i.e. to a different lighting when it is dark at night for instance) Overall it can be a nice addition to any computer, in spite of the high price tag, and the couple usability issues (fixable). There is hope these will get addressed (including the macro recording timing and the volume control wheel) in a next software/firmware update... Note: I probably should get this keyboard for free in view of the QA work done for Corsair! What say you?

I bought the Cherry MX version for $200 before tax. 5 stars, easily, but there's some stuff you should know before buying. The great stuff: - durable, high-quality build - beautiful to look at - the volume wheel is remarkably useful for games and videos - the clicky sound of the Cherry MX provides pleasing feedback - the wrist pad is very comfortable and attached securely with magnets Stuff you should know: - The K100 has two USB cables. You can plug your mouse into the keyboard, but you still need to plug the two USB cables from the keyboard into your computer. - Corsair does not seem to guarantee compatibility with any KVM switch. I took a chance on "UGREEN USB 3.0 Switch Selector 4 Port 2 Computers Peripheral Switcher Adapter Hub for PC Printer Scanner Mouse Keyboard with One Button Switch and 2 Pack USB Male Cable" (ASIN B01N6GD9JO), and it has worked flawlessly. In my setup, I plug the two keyboard cables into the front of the KVM switch, and run one USB cable from the back to my PC and another one out the back to my laptop. I have a mouse plugged into the keyboard. I do not run the monitor through the KVM switch, opting instead to have two cables from the monitor, one to the PC, and one to the laptop. - Coming from a rubber dome keyboard (Logitech G15), the keys on the Corsair K100 felt incredibly sensitive to the touch. As someone who uses the keyboard to write computer code, I initially found this frustrating, as a very light press on a key could cause a character to register many times (like "cccccccccccc"). I could see how someone might want to ditch the keyboard immediately, but after about two or three weeks, I managed to retrain myself to avoid those "heavy finger" mistakes. - I don't use the wheel on the upper left of the keyboard. I don't use the G-macro keys. - There are a lot of preset color patterns. I settled on one after the novelty of the options wore off. - I don't find the shifting color pattern to be at all distracting, even while concentrating on writing computer code. It's pretty. - The keys have stylized symbols, which can be a little unusual if you have to hunt for a rarely-used key or if a child is trying to type on the keyboard. The biggest offender to me is the ampersand (&) on the "7" key. The bad stuff: - Not much, except that the keys may feel too sensitive if you haven't used a Cherry MX keyboard before, and your mileage may vary as to whether you can adapt to one. So $200+ for a keyboard that may end up frustrating you could be a risky proposition. I read the terms for returning the keyboard, and it doesn't look like you can return it once you've opened it. (Maybe you can, but that's how I interpreted the terms.) So be sure that you like sensitive keyboards or have confidence that you can adapt. - There is a Corsair logo on the wrist pad that kind of looks like it is on a piece of tap that should peel off. It isn't. The placement of the logo slightly annoys me, but maybe that's just me. Overall, a great keyboard and a happy purchase.

There are some upsides and some downsides to the Corsair K100. I bought this after having used a Logitech G513 Carbon (Red Linear Switches) for some time. There are a few downsides about the Logitech that frustrated me, such as no dedicated media buttons and overly sensitive keys which made it very easy to type out a string of letters accidentally or inadvertently press something when your fingers were resting. With the Corsair K100, the first thing I had an issue with were the special function keys going down the left-hand side o the keyboard. Instinctively, I am used to quickly going to the top left of my keyboard to hit Escape or bottom left for Control. It's a built-in muscle memory, and those function keys got in the way and really bothered me. I think I could have gotten used to it after a while, but the other downsides were enough to put me off. For instance, the indents on the F and J keys were very hard to feel. They were not prominent enough, so finding the right hand placement was difficult. This is something that I can usually do on any keyboard blindfolded, but the indents were just not noticeable enough on the K100. I do as much typing as I do gaming so this was important to me. Although the keyboard ships with additional keys with better texture, (such as W A S D, among others), the J was not included and I need to be able to feel these to know I'm good-to-go when it comes to typing. I think what bothered me the most was the horrendous ringing sound the keyboard makes whenever you bottomed out a key. It sounded like a ringing bell, over and over again, with each keypress. The keyboard feels so cheap and chintzy sounding that I couldn't believe I paid over $200 for this. I know I can buy O-rings to help dampen the sound; and I know I can take the keyboard apart and put foam inside -- but why should I have to? I don't want to void any warranties, either. The keyboard felt like a piece of junk to be honest. The LED lights suck in comparison to the Logitech keyboard. They quality of the lights is just very poor. The profile you setup in the iCue software doesn't go into effect until you have logged into Windows, so during bootup period you have to stare at a random display of flashy colors that looks very tacky. Another issue I have is the font used on the keyboard itself for the letters and numbers. It's a hideous font in person. And the symbols next to the numbers along the top of the keyboard are so in-your-face that it's a distraction. Whatever Corsair did right, they did not get the aesthetics down of this keyboard correctly, that's for sure. The whole thing is really very ugly. On the plus side, the Cherry MX Speed Silver switches were very straightforward and worked perfectly. No keys wobbled at all, unlike the Logitech I'm using. There were no inadvertent double presses from resting your finger gently on another key. Granted, I only tested this K100 for a couple of days over Easter before returning it, but credit is due for the good key presses. The media keys are excellent. The volume bar and Play/Pause Next/Back keys on the upper right are simply great for listening to music and adjusting the volume for your game or music. The Logitech G513 is lacking dedicated media keys and I already miss these from the Corsair. In the end however, the bad far outweighed the good. I cannot justify spending $220 on what feels like a piece of junk. The additional function keys running down the left side are something I never want to experience on another keyboard ever again. I think the K100 is fine for younger gamers who care less about the feel of the keys and the typing aspect, or the aesthetics. They might even like the aesthetics. But it is certainly not for me. It should be a $60 keyboard, not a $200+ keyboard.

Let me tell you, when I say this is literally the best keyboard I've owned in my entire life, I mean it with every inch of my very being. This keyboard is absolutely PHENOMENAL. If you ever thought Razer had quality, then you need to set your eyes on this absolute beast. I can tell you, the utility wheel does not get in the way of your gaming. In fact, there's a lock button right next to the wheel that disables it entirely. However, as someone who draws a lot on a tablet, I LOVE the utility of the keyboard as a whole. I can adjust the volume without opening up the slider, I can preprogram functions on my wheel that I can use on my art program, and I can even change the music on my keyboard with the onboard buttons right above the keypad. Even if you don't have a lot of use for things like this, the keyboard itself is fantastic. I don't personally know a lot about specifics when it comes to what specs modern gaming keyboards have, but I really love the switches on this keyboard. I've always loved the clicky-claky tapping of a mechanical keyboard, so I was a little disappointed when I first started typing. Then, I realized, the sound of this keyboard is really therapeutic. The sound is so much more hollow, and relaxing, I feel like I want to write a book just for the sake of listening to the keyboard. Plus, it's a lot quieter, so you won't bother your friends as much over voice. The macro keys are always a plus to have, but they can sometimes get in the way, at least, for me, since I tend to use escape a lot. However, I do have a personal issue with the keyboard's design. The keys are sensitive. You might think it a weird problem, but given how heavy handed I tend to be with my resting hand, I find myself accidentally pressing buttons I don't mean to be pressing. At first, I also thought this to be a specialized feature-- you know, the ones that try to simulate a controller by lightly pressing on a key like you would slowly pushing a thumbstick. Nope. After trying it on a few games, it's simply just a sensitive stroke. BUT, don't let that deter you from the absolute quality this keyboard has. After switching from a Razer Blackwidow to this, it's SO much lighter, and thinner compared to it. A personal favourite I've come to love about this keyboard are the lights on the edge. Of course, that's a feature with Corsair's firmware, iCue, but putting an audio visualizer on it while you're listening to music is a cherry on top. I don't know what more else I can say about the keyboard, other than I love it. Quite literally the best money I've ever spent on a keyboard.
