K3 Version 2, 84 Keys Ultra-Slim Wireless Bluetooth/USB Wired Mechanical Keyboard with White LED Backlit, Low-Profile Keychron Mechanical Brown Switch Compatible with Mac Windows

I've used a lot of keyboards going all the way back to the original IBM PC. Most modern keyboards feel mushy to me. This feels great. I bought both the brown and the blue switch variations. The blue had a great feel, but its relatively high-pitched click was annoying. The brown is closer to a Goldilocks switch, quiet and with good tactility, although just a tiny bit mushy. I chose the K3 for its low-profile design, as I had read that the standard Keychron keyboards are very thick and need wrist rests. The K3 at only 7/8" thick feels fine without one. Key travel is also quite good. Fresh out of the box, I don't seem to have lost any typing speed compared with the MacBook Pro keyboard which I've been using for the last few years. I haven't had any problems with the Bluetooth connection. I have it paired with three devices – an iMac, a MacBook Pro and an iPad Pro. Just a few seconds each to pair initially, then no trouble with any of them. Switching between devices takes just a couple of keystrokes. As a Mac user, I really like that the media function keys work out of the box and are labeled properly. Likewise the command and option keys. I have no real need for the backlighting and certainly not for all the fancy, flashy chasing light modes. It's a keyboard, not a theater marquee. But I do find it handy to have on at minimum brightness when I have to work in a darkened room. If there's one thing I wish Keychron offered, it's a low-profile numeric keypad to go with this. I didn't want a full-size keyboard like the K5 which would force me to reach pretty far for my trackpad. But a numeric keypad comes in handy when I have to type in more than few digits, and it would be nice to have one to put to the right of the trackpad.

I love the slim design of this keyboard so much more than the previous K2, it weighs so much less and really skyrockets the mobility for myself. I’ve never liked the RBG functionality on these keyboards - it always seemed so out of place for it, so the white backlight only is perfect for me. I had switched from my previous K2 to a few other keyboards over the years but it was nice to come back to the K3 and feel right at home with the keyboard layout. I use both Mac and Windows machines so I love having the option to switch (I wish they made hybrid keycaps though!). The keys don’t feel lacking despite their new slim design, it still has excellent travel / tactile feel. Bluetooth is solid. I think its excellent quality and value for this model and Keychron really shows their care in presentation and design.

I had really high hopes for this keyboard, I was looking for something low profile, light-weight, and looks good/ergonomic for my office. The only down side which might not apply to everybody is that I had trouble hitting the keys. For some reason I struggled with typing quick – it just felt weird to me. Aside from that it is a perfect keyboard

great keyboard very easy to use and nice sound

Just got this keyboard today - typing on it rn. I had been using a Logitech G915 Lightspeed but after 2 of them malfunctioning, and being very expensive ($150), I decided to look for a replacement that was more affordable and hopefully wouldn't break within a couple months. So far, it feels pretty good, maybe a bit more actuation pressure than I expected but that's probably because I tried the brown switches vs. reds. It fits the ultra-slim profile perfectly, typing feels good, the lighting is pleasant, worked right out of the box wired + bluetooth in seconds. It comes with a couple key caps for Windows + Mac change out. The color swap of the backlight doesn't appear to work as the instructions lay out (Pressing 💡, then fn + ⬅️/➡️ -- or just the fn combination). Caps Lock turns red when toggled which is nice (believe it or not, not all keyboards have an identifier...). The real deal will probably be in a few months - hopefully I won't have to update this review because keys stop working or have repeated entries via a single key press. Even if it does -- the pricepoint is quite good compared to the G915 I had.

Keyboard is SLIM! But feels incredible to type on. Highly recommend the brown switches. This is of course subjective, but again, for me, feels great.

Update - 2/12/26 I really want to love this keyboard. It would be perfect if it actually worked. The first one had issues with its battery life, then with the keys sticking. I tried unpairing it from my PC, and repairing it. Didn't help. My two other options were to tear the thing apart to try to flash the BIOS (which is not recommended by Keychron because you can brick your device that way) or buy a new one. So I bought a new one. The lights won't stay on at all. Unfortunately, I'm dropping my review down to one star and moving on to a Redragon keyboard. I don't like the size of the Redragon, but at least it's working. Ultimately, I recommend that you find a different keyboard. ------------------------------------------------------------------------------------------------------------------------- I've been using this keyboard almost daily since mid-July. I like the size, the look, the feel... pretty much everything. Unfortunately, the battery only holds a charge for a few days at most. I thought I noticed the decline within the first month, but I wasn't keeping track of it (it was brand new, after all.)

After watching a Bitwit video where he said this is still his favorite travel keyboard (he was flying), I found an open box of the same model and figured I'd give it a try for not only my laptop but a SFF for travel. Kyle was spot on. I absolutely love this keyboard. For the price, it is better than many more expensive models (I'm looking at you Razer). The value is fantastic. Unlike many portable keyboards, it has much better key travel along with both Bluetooth and USB capability. Good click, backlighting and quiet sounding keys. I like it so much I plan on picking up another one for my wife to use with her laptop.
