just got this one. not great so far. half the prints are failing. hopefully these are just kinks that can be worked out. machine is compact, looks good, looks to be high build quality. software is excellent. even has stacking feature, though that part's not intuitive at all. open system, and has a lot of resins that are pre-tested and configured already. it has a really nonsensical resin tray system. you can't use trays until they're worn out, you have to replace them after a certain amount of use, depending on how much you paid for it. basically amounts to licensing fees. you have to throw out perfectly fine trays, and if trays die early you have to save the rfid tag to use on other trays. colossally stupid, if you ask me. the tray bottom seems to be nothing but a layer of silicone. it's not very durable and it didn't take much to put a hole in it. still early. will need to revisit later. so far, mixed results.
