OK

On the one hand I'm happy that Keychron make ISO boards and include UK keycaps, on the other hand it's really annoying that they give us these crappy shine through keycaps and not the nice double shot that the ANSI crowd get. I also with Keychron made it clearer which switches were compatible. Do not order optical switches with the Pro boards, they are not compatible!

Mostly very good

Great action, my fingers can really fly. The keys are slightly larger than my old full-sized keyboard, which takes some getting used to.

It's noisier than I'd hoped considering I went for the red switches. Also the keycaps get very shiny, I think they used to use the higher-quality plastic but for some reason have switched to the cheaper stuff. Pairing and switching Bluetooth is annoying as there's no visual cue that I've seen. The base is plastic even though the sides are aluminium.

I'd have preferred the K1 Pro but they don't do a UK layout for it. Overall I'm happy with the K3 Pro and would purchase it again.

Worth the money

A nice feel and not too hard to program. So much better than cheap ones.

Awesome portable thunker

I have to say this keyboard is excellent in every way. Weighty, low profile, fabulous key feel (with the browns), responsive and with cable or Bluetooth options at your fingertips). Keys are easily changeable and a good selection of alternatives between UK ISO and US in the box (along with a decent a-c cable, key and switch removal tools). I also purchased the wooden wrist guard which is a perfect fit and very comfy.

I also found the key programming software fairly easy to use.

And it sounds awesome too!

Program with QMK & VIA.

QMK/VIA means endless possibilities for a fluid workflow. Thanks to our engineering team, it's the first time in history that a wireless mechanical keyboard has these kinds of capabilities right out of the box.
 
Simply connect the K3 Pro 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).

Check out the video above demonstrating how to remap the Light Effect key (located on the K3 Pro’s top right corner) to an Eject key with the VIA software, so you can get a shortcut to put your Mac to sleep (Command-Option-Eject), or even remap the fn key in a breeze. It’s never been so intuitive and flexible to personalize your own keymap.
 
An ultra-low-power ARM Cortex-M4 32-bit STM32L432 MCU which is powerful, and equipped with 128K Flash will provide more flexibility for developers.

Suitable For All Devices

Offers a Mac layout while still being compatible with Windows, the K3 Pro is one of the few on the market that has the same multimedia and function key functions as Apple keyboards for Mac users, but with more tactile feedback.
 
You can even configure different keymaps for both Mac and Windows devices. While VIA software is compatible with macOS, Windows, and Linux. Includes keycaps for both macOS and Windows (and additional esc and enter keys) to allow you to switch between operating systems with ease.

An Epic Core Inside

A powerful ultra-low-power ARM architecture MCU equipped with 128K Flash will provide more flexibility for developers. The polling rate is 1000 Hz on wired mode right out of the box, which makes the latency hardly noticeable even in competitive games.
