Keychron Keyboard UK Layout k3 version 2 low profile keyboard

love the keyboard, first time buying Keychron, always wanted it but wanted to wait for the correct version. i got the K3 Wireless keyboard version2. light keys, quite, small and compact, 80% keyboard does what i need when i travel into work as i dont want to take large keyboards whilst traveling. the Bluetooth is amazing believe its bluetooth version 5.2 with instant connection onces turned on. easy to remove key caps to remove UK ones. really can't fault it. just feels amazing and defo recommend it an it looks so beautiful. also i haven't got a case because the box already has production pads inside so that's also really good. i didn't get the RBG version as i dont like multi colours as the white light is good enough for me. uses usb to charge and not battery even better. and you can use cable mode or wireless. and the wireless has really good reaction time as well and no delay and miss registered key input. amazing.

Good quality, not what I'm looking for

The low-profile switches feel great and the build quality is solid. However, I've realised that I don't enjoy the compact form factor. I would love to buy a K1 (low-profile + TKL form factor) but unfortunately it only comes in US layout. When I asked if there were plans to release the K1 in UK layout I was given a firm "no" - extremely disappointing. For now I will be returning my K3 v2 and asking for a full refund.

Issue with bluetooth

The keyboard is great in all features but 1. If you’re connected the the keyboard via Bluetooth and you don’t press anything for a few minutes it’s partially disconnects. You have to press a button, wait 2-3 seconds for it to reconnect and then you can start typing again. The keyboard needs a receiver

HOT-SWAPPABLE

We all have our unique typing preferences, that’s why we went the extra mile to make the K3 the world's first hot-swappable low profile Optical switch keyboard. We’ve implemented a MX-styled stem and stabilizers, and conducted numerous design iterations of the keyboard structure.

You can easily hot-swap every Optical switch in a few seconds to customize your typing experience on the K3 without soldering. *Hot-swappable feature is available for low profile Keychron Optical switch version only.

Optical Switch

With the MX-styled stem housing and 0.2ms ultra-low latency, the low profile Keychron Optical switches are crafted for typists or gamers who want to type at lightning speed with a 70 million lifespan much greater than industry standards.

*Low profile Keychron Optical switch keyboard is not compatible with any conventional mx style mechanical switch.

ALTERNATIVE KEYCAPS

We’ve spent over a year developing and implementing a MX-styled stem on both the low profile switches for the K3 as well as stabilizers on the big keys like the space bar, left Shift, backspace and Enter key.

It will improve reliability, deliver better typing experiences, and may potentially pave the way for other keycap manufacturers to launch alternative keycaps.
