Finally built mine. Overall, super happy. This was my first group buy of this type so was a little skeptical, especially towards the end with covid but overall very solid board, so props to senter. 
Some random thoughts..
 -The PC finish/polish is flawless. I have no other experience with PC boards but from what I've seen on other runs, it isn't easy to get a perfect finish. Even the inside is flawless, no machining marks, scratches, etc.
 -After seeing some early builds with the PC plate looking like swiss cheese I was worried but my plate is perfect. Alu plates looked good from the start but same idea, e-white finish is flawless.
 -Really wished I had gotten the key logo right blocker.  

 -Gaskets were pretty straight forward, little skeptical of the longevity of the adhesive over time but there are a few extras in the pack.
 -Reset button was pre-trimmed but it still clicked when I was pressing the plate to test flex. NBD just de-soldered it and its been fine. 
 -As mentioned above, the rubber damper isn't cut right for hotswap PCB stab direction but easily trimmable. 
 -Just a personal issue/quirk, the typing angle+PC plate with no damper = LEDs straight into my eyeballs lol.
 -Reprograming was a super easy. Followed senters directions of flashing the hex from caniusavia with qmk tookbox and VIA worked perfectly (First time using VIA, but not QMK toolbox).
