It's a shame such a beautiful keyboard has such shitty mounting. That is my only complaint, but its a huge one.
First, The mounting of the USB C daughter board was too tight or something, much like @Igarashi below. However, for me, not one of the keys on the board worked. After removing the daughter board and retesting with it unmounted, all my keys worked, so I hope to be able to remount it with the right screw pressure to allow it to continue working.
Second, as others said, the mounting of the PCB is complete shit. Whoever thought top mounting a hotswap PCB with only 4 screws from the PCB to the plate over a full size keyboard has obviously never designed a keyboard before. The good news is that the top mounted plate feels solid, as a top mounted plate should, so once you have your switches in place, they will stay and feel just fine. Getting them into place, however, is a separate task entirely. Again, as others said, the PCB warps horribly, especially on row 5 (spacebar row) and on the far right by the numpad.
I did not have any issues with the hotswap sockets disconnecting from their solder joints, however, there is not a lot of solder on any of the joints, so I can easily see why others are having issues with them.
If it weren't for the mounting issues, this would easily be a 4-5 star keyboard. It's absolutely beautiful. I would only drop it to 4 stars if the software (again linked below by @SpencerL) doesn't work well or is missing features. I may update that in the future. However, with the mounting issues, I have to give it 1/5 out of the box and up to 3/5 once fixed.
I'll post a picture or two once I get GMK camping installed.
Not sure what artisans to put above the numpad just yet. Board sounds and looks great, so now that it's together I'm very happy with it, but putting on switches and getting it working should not have been so hard.
CaptainPunchIt's ok, I'm actually typing on it now, since I needed a numpad recently. As I mentioned in my first post, once it's set up, it's great. Also as seen in the picture, its still a beautiful board.
However, the right Windows key and context key still don't work, along with numpad 3. I don't use any of these keys, so I haven't opened it up to see if its a bad solder job, or what.
My suggestion is still the same when I first got the board. If you want a working product, out of the box with no hassle, avoid this. If you are willing to put up with and troubleshoot some (fixable) issues, and prefer the look of this board, go with it. It's still very much a 3/5 with the issues, but it makes up for it with its looks.
