Kingroon KP3S vs Prusa I3 Mmu2s

This printer has a niche for me it repeatedly prints 10 minutes parts very small. However a few times has frozen on me and it could have potential for parts that last 3-4 hours but because I had it freeze intermittently about 10 times so far in two weeks really makes it unreliable. Even with that I ordered a second one to get more tests done. Another thing is that Kingroon actually sell all metal heat breaks on their website for their particular printer and you can upgrade this

It is just not worth it for having to just return it after that from what I know. like I said, fifty percent and fifty percent. If you're one of those...
