This is a really lazy implementation of this idea.
I briefly considered making one of these for my electronics company https://store.n8ech.com, but found that there are plenty of available options like the AhaKey https://finalkeystudio.com/products/finalkey-x-ahakey-x1-vib... out of I think the Philippines.
This one is going to be a pass.
The technology seems light years ahead of Keychron, definitely a game changer.
Keyboard parts based macropads are the original idea and have been around long before AI. Single purpose marketed versions are the lazy implementations - you can already get any keycaps you want and swap them on to your 10 year old macro pad (or spend a little more for ones with traditional screen based buttons).
