I built my first keyboard on this case, with Boba U4T's and Akko ASA keycaps. I have to say, I really do not have any problems with this board, apart from the fact that it cannot be remapped (although the PCB is based on a GK68 in some way, the epomaker software relies on a direct USB connection which this keyboard doesn't have).
Of course, the silicone dampener and the included foam are great (I added more foam but it barely fits), and after lubing the plate mount stabs with some dielectric grease, it sounds pretty good imo (even the stabilised keys). The translucent black case look great in my opinion, and the plastic is decently thick and feels very solid.
I had to pay $13 USD shipping which increases the price significantly, but it is still worth it. Also, you can find other tester 68 keyboards in other colours on Aliexpress, so you may want to consider those too.
I recommend this for anyone who wants a great value and decent keyboard, but also doesn't mind not having a wired connection or the ability to directly remap the keys. I may consider doing a bunch of soldering and replacing the microcontroller module with a programmable one!
