The vat cover is flimsy - I have 2 vats, and in less than 3 months, one of the covers fractured and broke. I plan to print another cover with my FDM printer.
I also would have enjoyed a bit more slopes in the perimeter to let the resin go back in the vat naturally.
The rest is fine - the vat slides well into the printer, it's easy enough to wash the transparent film, and the structure is functional.
