- Excellent job
- The font choices are bold. They don’t appeal to me personally, but nice job.
- The sunk/raised key caps look nice but I’m not sure how they would perform in practice.
- I couldn’t tell from the website what the second switch on the site does. Maybe USB/Bluetooth?
- My strong preference is a key command for switching from Bluetooth/USB, and that the keyboard keep both active for instant switching. The only keyboard I’ve found that does this well is the micropython-based M60.
- I’m not a fan of the look of the dial. It sticks up too far and looks like something that could break.
I almost couldn't believe that was the cause, but when I waited for the device to turn around again, that was definitely it.
I don't even have to look at my fingers often, but I wouldn't be able to stand walking by those numbers on a regular basis. I don't think I've ever had such a visceral response to an aesthetic choice before.
- the rotary encoder. I don't see what the aim of this is - what's the intended usecase?
- the font on the numbers. I feel like it should match the font used on the other keys instead, which I think I like but it's hard to tell because there's no good actual picture of the keyboard as a whole
- drop the model name on the right. I get that you've made a keyboard that is a design statement, but it would bug me as an owner. Move it to the bottom.
edit: for context, I already have a not dissimilar in terms of concept Keychron K3. That puts page up/down/home/end in that blank space on the right where you've put the model name. It does make the keyboard feel more cluttered, but I do find myself using those keys frequently.
oh, and is it backlit? I am assuming not from the specs, which is unfortunate. an understated, not too bright, white only backlight would be really nice to have on a keyboard like this.
I actually have a separate USB rotary encoder next to my keyboard. Glad to see it integrated into the design. It's like a more comfortable mouse wheel. If you need to scroll a lot (editing audio, for example), the constant "scroll a little, lift finger, scroll a little, lift finger" routine gets old real fast. But if you've got a wide enough knob, you can just spin it around indefinitely in one circular motion.
The sticking-upwards knob makes the keyboard harder to transport though. It definitely risks to be broken off when put into a backpack.
I even had to google images of your espresso machine to see what you were talking about. Wow....

EDIT: You could for example reconfigure the slider to switch between BT profile 1/2/3, and have the board auto-switch to USB when plugged in. Would take ~2min for me since I know my way around ZMK, bit more if you have to dig into how ZMK works first ofc.
Did you consider adding a small screen?
I've always hated bluetooth keyboards until I built a Zaphod (which also runs ZMK). And just being able to see battery estimate, whether it is trying to pair, or which device it is currently connected to has made it a much smoother experience.
One bit that I find helpful is that the keycaps are all the same height/angle so that I can rearrange them... hopefully..
Same for the pronounced bump on the home row.
The switch is to choose between one of two Bluetooth devices. I agree the placement of the USB label was confusing there.
I can't really tell if the numbers are in a different font than the rest of the keys, but if they are, I'd dislike that too. Please use a single font for the whole keyboard.
Aesthetics are a major selling point for your keyboard, so I think you need to spend more time and get expert advice about the fonts.
Finally, this is evidently a Mac-oriented keyboard, given how the control keys are labeled. If you plan to target the Windows market, you may wish to provide layouts with Windows-oriented control keys that are labeled as such (namely Ctrl, Alt, and the Windows key, or something that looks like the Windows key.)
Epomaker's keyboards also do this, at least my SK66 does. Fn+Space switches between wired/BT and Fn+[Z|X|C] switches between the three BT connections. It also flashes blue on the active connection so that you know you've switched into BT mode.
