Great keyboard at a good price

This is my second K3 (the other was v1). So far so good, the only complain for v1 is battery life, which we’ll have to see for v2. But typing experience is better with v2.

Love both my Keychrons

I ordered a K3 with the brown switches (and extra blues) first. I loved it so much I ordered a K1SE with Mint switches (And extra oranges).

So right now I have Keychron Low Profile Optical Switches in:

Brown, Blue, Orange, and Mint.

The Mint’s are great for their “weight” but I didn’t like them as much as the browns. The Blues were nice but a little too lite. The Oranges have the weight of the browns with the click of the blues and I swapped all the mints out of the K1 to the orange switches.

So for those keeping track… K3 with browns and K1SE with oranges.

Build, feel, and use are excellent. I actually look forward to working because I get to use these keyboards every day. They keycaps are comfortable and good looking as well.

I cannot comment on the battery life as I keep them tethered with the USB cable.

The colors on the RGB backlight are great.

Overall I love these things and I have recommended them to everyone I know that is willing to listen to me gush about keyboards.

Nice first mechanical keyboard

This is my first mechanical keyboard and in general I really like it, it’s low profile so I don't get wrist pain and I can use it for long periods of time. Because I work on an office, I got the keyboard with red switches, but they are too mushy for my taste so I got the banana ones and they are perfect (not too mushy, not too clicker). I give it 4 starts because of the keycaps, they get fingerprints easy (the greasy type of fingerprints), and they will get shine through time. Also, you can’t change some of the keycaps because of the stabilizers, so if you like to personalize keyboards you should search another model or brand.

SUITABLE FOR ALL DEVICES

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.

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.
