Just got it, and as a matter of fact, I'm using the little guy to type and it's all I could've ask for in this keyboard category. The only reason I had to knock off one star from an otherwise perfect score is the lack of information on how to get this to work as when you have no idea that they keyboard will not be recognized by your PC unless you use a USB cable that has USB-A to USB-C. Just imagine the excitement of getting to type your very first character only to be faced with NOTHING happening --> My laptop is of recent build and only has USB-C ports, so I was using a USB-C to USB-C cable which now I know was the cause of the anticlimactic first experience. Forget about finding proper documentation in the box, just a QR code that also leads to next to nothing in the instructions department. Was very bummed out and decided to connect to an old chromebox with that had USB-A and to great relief the little guy came to life. Nonetheless that first experience has gone sour already. Fortunately, I had an adapter that allowed to connect to my laptop and here we are. I was tempted to give it 3 but after all, it all stemmed from a lack of information and not a defect. If we are to go purely by the product itself, it's a perfect score.

Having received just today morning in South Korea, thank you for the safe packaging.
first, it was quite hard time to get used to typing with this smallest keyboard I've ever had, and I still don't know where the "Caps Lock" key function is.
I hope you supply A Good Manuals to use it, and this is quick guide for the users.

there are 3 lights on the left side of this keyboard, from the top, this order below;
1. Fn key function ON/off (toggle)
2. Pn key function ON/off (toggle)
3. Scroll lock function ON/off

and Pn key(left) is for blue printed key function, which is left position of keycaps printed,
on the other side, Fn key(right) is for red printed key function, which is right position of keycaps printed.

I hope get my answer for "Caps Lock" key function, and my quick guide would be helpful for the next customers. **MK Note - Press Pn+Tab to turn on/off Capslock.**
