Almost perfect

I've got the K3 Ultra-slim with red switches. There are only a few things I don't like. In general it's simply great.

Pros:
I like the key-travel. It's not too far, not too short. For example I've got the Logitech MX Keys, too. It's a great keyboard for typing, but the key-travel is too short for gaming. The K3 is perfect.
I ordered not the RGB-Version because I just wanna see the keys. I don't need a disco under my fingers :-). The lighting is really good. Not too bright, not too dark.
The build quality ist great. It's sturdy. It feels really great. A good weight, so it doesn't move on my desk. But not too heavy to break my desk. Perfect!

Cons:
I don't understand why the F1-12 stays dark. The "Apple-Signs" on the F-keys are illuminated but not the F-numbers. Not everybody who owns this keyboard is an Apple-Fanboy...
I miss a little "bumper" on the W-key like on the Roccat Horde for example. I mean this little thing to feel like on the F-key and the J-key. This would help a lot if you are a WASD-Gamer.
I don't know why the powerswitch is in this order: Bluetooth - Off - Cable. It's a little bit tricky to switch it from "Bluetooth" to "Off" instead of "Cable".

In general it is what I wanted it to be. A small keyboard with less space on my desk, wireless and a great typing experience.

Do I recommend it? Yes of course! If my Cons don't bother you.

Great product, not for everyone

The product is awesome. Really like the quality and brand. I find the keyboard layout itself it slightly too cramped for me and I find myself tapping other keys accidentally. Its a pity as the size is amazing. I will probably try the K8 and try and Ebay this one.

The perfect combination

Portable, wireless, optical/mechanical low profile keys. It is well build, has a greate feel when typing. I wasn't sure if I made the right decision, but after the first couple of days and then weeks, I have to say, it's perfect for me.

best keyboard I have had

I was an avid mechanical keyboard user before I switched to Apple products about 10 years ago. Then I fell in love with low profile key caps (granted Apple overdid that one). Now I have the option to use lowprofile keys and mechanical switches. I am in love.

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.
