Love it but

I love typing on k3 with brown switch, the only issue is the battery. Hep the battery really sucks, even no backlit on it nearly last 2 days, I am typing a lot in a day but I was expecting something as good as my K1. Anyway baby there is a way to upgrade the battery. It is a great keyboard and for the price it is awesome.

Wonderful typing experience

I've always liked flat style keyboards such as the MX Keys. I apprehended the Keychron but wanted to understand the hype. I have never been more wonderfully surprised by a keyboard!
The typing experience is amazing and is so satisfying.
The simplistic design fits well in my desk setup.
I thought I would like the red switch better since they have a gentler and quieter profile like I'm used to on my non mechanical keyboards but the reds felt too mushy and weird and I would make a lot of accidental keystrokes. The brown switch is perfect for me on the Keychron K3.

I give it a five stars since I am very satisfied with the keyboard but I think the following should be improved:
Battery life - even with the RGB lights always off, I have the charge the keyboard every two weeks.
A software companion would be very welcomed for app specific key mapping - example on app development software, I would like to use the function keys instead of media keys. Having to press FN+Fx key everytime is quite tyring, specially since I'm constantly swapping between apps.
The key caps collect finger oil and become shiny and the oil prints are visible. Can you make oil resistant key caps please?

Overall great keyboard that comes highly recommended!

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.
