I have had this for about a year now. The only problems I have had are, in order of severity, the print surface sticks on too well tot he print. I just damaged it as a part, when flexing the plate to remove it, took part of the plate with it. Yes, it is that sticky to the prints. Number 2, I had to replace the head as the insulation tape around the nozzle got messed up due to a print failure. This eventually led to a nozzle & head clog. I bought the replacement which uses silicon instead so I don't anticipate any further issues.I print in PETG at .12 layer and I get such smooth prints it is awesome. The picture is what is printing today. Great detail on every print. HIGHLY RECOMMEND the Ender series. Go for the pro, it's even less than what I paid for the standard.
