Received this and while the package was a bit crushed. I believe it was shipped from China so I suppose it's a tough journey. That said, there's lots of foam inside so the Keeb was fine. I had some cherry browns ready, plugged them in, put they keycaps on and.....like 1/3 of them didn't work. If it had just been 1 or 2 I might have believed it was an issue with the board, but when a random nearly half of the keys didn't work that seemed suspect. So I pulled the keycaps off, then the switches, and discovered I had bent the posts on half of the switches. Since I had simply jammed each one into a socket while watching YouTube I was, in retrospect, not giving delicate parts the attention they deserve. I replaced those switches (carefully), and everything worked fine.
The VIA software is pretty intuitive, and the capability right out of the box is really pretty thoughtful, there were a few things I hadn't expected: layer passthrough, tons of different layer toggle options, and the ability to map arbitrary functionality to the knobs. The default RGB patters are unreal... the last backlit keyboard I had was 5 years ago and the progress since then is wild.
Unfortunately the manufacture has elected not to opensource their QMK layout/keymap. Someone apparently figured out DOIOs 16 key board and created a keymap and layout for that board, so hopefully this one will follow.
