Nice heavy case, clean uniform textured surface and good machining with no sharp edges. Came in nice packaging with some extra screws. I have the 2u shift kit and it's a quality kit but with some minor issues. The pcb was fine and for the most part worked perfectly soldering and flashing QMK. One small thing was that I couldn't get the "up arrow" key switch (second from the bottom and right) to get into the board without clipping the left pin on the switch, but after assembly it works fine. The plate worked well, it was a bit tricky to set up the bottom two rows because of how many different layouts are supported, making the plate very vague and having to manually make sure the keys weren't crooked. Fully assembled the kit works great and I used some of the light foam in the packaging to put in the back of the case and it sounds nice and solid. I think due to the plate there is a bit of flex in the bottom row, but the rest of the keyboard feels quite solid.
Excellent build quality, impeccable finish. I'm very happy with the purchase. and it arrived very quickly to Portugal, it took almost 2 weeks. DZ60 pcb fits perfectly. 100% recommended!!
