Great keyboard

I love this keyboard ! I buy it with brown switches and touch and sound are fantastic.
Received in France from China in ~10 business days. The design and the size are perfects.
Just a little comment for future releases, I switch the 'esc' and 'caps lock' keys (like some other people) but the 'caps lock' is highlighted in red. I think it will be better to can disable this feature.
I tried the bluetooth under Ubuntu 20.04 and it's discovered without any specific configuration and very responsive.
Some fn function doesn't works well under linux like 'fn-F3', 'fn-F4', and the keyboard highlight with 'fn-F5/6' set the light of my keyboard laptop but not the Keychron (but it's not very important for me).

❤️ I like my new keyboard ! ❤️

Could be improved a little, but just a little...

Ergonomics: *****
Bluetooth conectivity: **
Wired: ******
Battery Life: *
Stock Switches: *
Banana/Mint Switches: *****

How to improve it:
A more stable Bluetooth conectivity.
A 2.5GHz conectivity option, even if it means adding a wireless plug.
Double Shot keycaps, even if they still are ABS, douybleshots are way more durable and long lasting than painted ABS.
There are Batteries with half the stock battery size and almost the same power, and under the PCB there is plenty space to put 4 of those so....

Sumarize: Good Keyboard, great as a base to add some improvements to get the perfect experience and with a bit of investment, comparable with Q series but Keycron trully need to improve its bluetooth connection stability to make it perfect.

Game changer!

I'm a reasonably accomplished typist (sustained 100+ wpm with peaks to ~140) and cybersecurity professional - needless to say lots of typing. Evidently I'd never used a truly good mechanical keyboard before - this has been an absolute game changer for me. The form-factor is outstanding and it is a total pleasure to type on. I came from an Apple Magic Keyboard which was very good but this is a huge upgrade. I didn't know what I was missing until I made the switch! I went with the brown switches and, while definitely clicky, the sound is fairly modest. I work from home, but I think these switches wouldn't be a problem in an office setting. 10/10 would recommend!

Best Keyboard I've Ever Used - But Terrible Placement of Light Key

I've been a Keychron user for the last 4 years, starting with K1. This is now my 3rd Keychron keyboard. The K3 has a smaller footprint vs K1, and the red switches are notably quieter. The K1 has flat keys, and the K3 keycaps are more rounded, making it easier to touch type. The spacing between keys is actually better in K3, and I have a lot fewer keystrike errors.

The one fatal flaw with the K3 backlit version is the placement of the light key. It is in the top right corner right on top of the delete key. The delete key is one key that I strike without looking. With the K3 you have to constantly look to make sure you are hitting the delete key. Otherwise throughout the day you will mistakenly hit the light key. The other frustrating part is that most other keys on this keyboard can be reprogrammed. EXCEPT the light key. A workaround that I use is to remove the light keycap and switch, and tape over it with a small piece of cardboard. Looks dorky but it works.

All of the other Keychron keyboards do not have this weird placement of the light key. But apart from this, everything else is perfect with K3. The white (nonbacklit) version of K3 does not have the light key for obvious reasons. But this only allows for mechanical gateron switches and is not hot-swappable. I much prefer the optical red switches.

Keychron if you are reading this: Please come out with a hot-swappable version of K3 nonbacklit. Or just take the K3 and get rid of the light switch in top right corner.

I love this board but I'm so used to having the delete key top right that adding a shortcut to swap the Light and DEL buttons would make it perfect!

ERGONOMIC ANGLE DESIGN

Two level adjustable rubber feet makes the new K3 more comfortable to type on.

SUITABLE FOR ALL DEVICES

Keychron K3 ultra_slim Hot_swappable wireless mechanical keyboard Mac Windows iOS Android Keychron low profile Optical and Gateron low profile mechanical switch alternative keycaps

Compatible for both macOS and Windows. Keychron is one of only a few in the market that comes with a Mac multimedia keys layout for Mac enthusiasts (Check high-res keycap layout and size here). For Linux users, we also have a dedicated user group to help with the experience.

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.

MECHANICAL OR OPTICAL?

We’ve overcome different technical challenges to redesign both the low profile Gateron Mechanical switch and low profile Keychron Optical switch in order to elevate the typing experience while enhancing its reliability on the ultra-slim keyboard.

Mechanical Switch

Durable low profile Gateron Mechanical switch with a 50 million keystroke lifespan to provide an unrivaled tactile responsiveness

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

Keychron K3 ultra_slim Hot_swappable wireless mechanical keyboard Mac Windows iOS Android Keychron low profile Optical and Gateron low profile mechanical switch desktop setup

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.
