A fellow in our makerspace has the Robo 1 and absolutely loves the printer. The quality of the prints he shows is good and the printer has been generally reliable. He's lost the heated bed and doesn't care, although I've offered to help him troubleshoot the problem. He likes the printer sufficiently to want to purchase a second one, but they don't appear on the market much anymore. The newer models don't appeal to him at all.

I've worked on the printer with him, although I can't recall why. It's easy to take apart for any reason, as the outer shell is decorative only.

I've not read anything good about the DaVinci, but that's just a vague recollection.
