Review: best keyboard of its type - This is probably the best keyboard of its type on the market. Great quality.
Review: A lovely keyboard to type on, with some quirks. - This is a real pleasure to type on, but of course, that's the main reason to purchase it. I have only had it for a short time so I cannot yet comment on durability but all keys operate flawlessly at this point and of course the whole purpose of keyboards like this is that the switches are easily replaceable in any case. However there are some nitpicks. Firstly although purchased as a UK keyboard and used under Windows, you have to swap quite a few more keys than just the two or three on the quick start guide to get the layout set up like a standard UK keyboard. You do, of course, get all the required keys with the keyboard along with a handy tool to remove key tops, so this is a fairly minor issue. Just a bit odd to be purchasing a keyboard marked as UK, and have to do this. Secondly the keyboard lacks an 'insert' key. Now this is quite important to me and after reading that supposedly pressing fn+del is supposed to be insert, I was very puzzled that this did not work. Subsequently I launched the KeyChron Launcher, which is a a browser-based tool for customising the keyboard. You must connect the keyboard either via WiFi or the supplied USB cable to use this utility. Then remember to switch to layer 2 if you are using Windows, otherwise changes won't work. It was then easy to repurpose the lightbulb key next to the del key as an insert key, since to be honest I really don't need the RGB backlighting, I just wanted the mechanical keyboard switches. Changes you make are permanent, you do not need to keep the launcher page open after you modify the keyboard mapping. A nice touch is that you have two layers of mapping each for Mac and Windows. This means you could set up an entirely customer layer for specific applications, which could be useful. Another issue to be aware of is that the caps lock key has no real visible indicator when it is on, because although the key LED lights up red when caps lock is pressed, you cannot see this from above. Note that the keytops do not have transparent (or indeed translucent) letters so the backlighting only appears around the edges of the keys. Also no matter what colours you set the backlight to, with the backlight off, the key cap LED is always red (not, as I said, that you can really see it). I am not really sure what the purpose of the backlighting is, to be honest, I get that it's a 'gamer' thing but while it would be useful in low light conditions that would only be the case if the keytop legends were translucent - which they are not. Finally you may find yourself accidentally hitting the print screen button as it's positioned just above backspace. Fortunately you can disable its default action to invoke screen snipping in Windows and still have ctrl+alt+printscreen to copy the screen to the clipboard. As I said, these nitpicks aside, it's a superb keyboard to actually type on, with proper mechanical keys and a decent travel. It's not too noisy and not 'clicky' like an old-school buckling spring IBM keyboard, but it is definitely not as quiet as a standard laptop keyboard.

## Features

- 2.4 GHz & Bluetooth Connection: Experience peak gaming performance on the fly with the 2.4 GHz wireless connection boasting a rapid 1000 Hz polling rate. For seamless multitasking across your computer, phone, and tablet, you can effortlessly connect the K3 Max via Bluetooth 5.1 to three devices.
- Hot-swappable Support: The pre-installed low-profile mechanical linear red switch provides unrivaled tactile responsiveness with up to 50 million keystroke lifespan. You can easily hot-swap every low-profile Gateron mechanical switch in a few seconds to customize the typing experience without soldering. Note: The K3 Max is currently compatible with Gateron low-profile mechanical switches only, as QMK does NOT support low-profile optical switches.
- Ultra-slim Wireless Custom Mechanical Keyboard: Anyone can master any keys or macro commands on its 75% compact layout through VIA. It has included LSA (low profile spherical-angled) profile keycaps for both Windows and macOS.
- With QMK and VIA Support: Keychron K3 Max allows anyone to remap any key, and create macro commands, shortcuts, or combination keys through VIA. Simply connect the K3 Max to your device with a cable, drag and drop your favorite keys or macro commands to remap any key you want on any system (macOS, Windows, or Linux).
- Supports Wireless and Wired Mode: You can connect the K3 Max with up to 3 devices wirelessly via its stable Broadcom Bluetooth 5.1 for seamless multitasking across your laptop, phone, and tablet. Switch among them swiftly. The K3 Max can last up to 78 hours (at backlit off) with a 1550 mAh battery. It also has USB Type-C wired/2.4 GHz mode with 1000 Hz polling rate (Wireless Bluetooth: 90 Hz).

### ⭐⭐⭐⭐⭐ A Truly Good Low-Profile Option
*by A***N on 8 January 2026*

I'm a big mechanical keyboard guy. I've had many over the years, but recently I've been leaning more toward low-profile. I came from a Durgod Hades 68, which was great, but I wanted something wireless. My first port of call was the Lofree Flow Lite84. Can't say I was a fan. Looked and sounded delicious, but the switches were far too easy to press and accuracy really took a severe hit so I returned that. Next I went to the Logi (gross, I know, but here we are) MX Mechanical Mini and for all its faults, it hit the spot. It was accurate, didn't look too bad, and did the job. The sound, however, wasn't the nicest and it was somewhat flimsy. Recently, since OS Tahoe, the Logi app no longer works and Logi seem hellbent on losing customers by not fixing it and not responding to the issue in any way. I should have know better, to be fair. Enter this, the Keychron K3 Max. Fantastic. Looks good. Sounds good. Feels good. Accuracy is pin-point. The banana switches are, for me, the perfect middle-ground between clicky and not too loud. Honestly can't fault it so far.
