I have one. Ironically, it is crappy quality control in China, but for the price, it is great. I have had no end of issues, but I think I got a lemon. Five guys I work with don’t have a problem with theirs.
Someone told me there are twenty factories in China producing them...don’t know if that is true.
When I got mine, first thing I had to do was break a part off of it according to knowledgable YouTubers. That’s hard to do, even on a $200 printer.
I meant to say twenty factories that have no communication between them about issues, improvements or even standardization beyond the plans.
I kind of have a hunch that is true.
