From my experience it’s definitely not as bad as described there. Yes, there are some issues here and there but still a 3D printer is an awesome tool to have at hand. I often designed / printed spare parts and fixing something on a Sunday afternoon spontaneously without much planning and lead times for a third party feels pretty awesome. I would say in 8 out of 10 times I can just plug the printer and start using it without issues. In 1 out of 10, I have to do some small tweaks (e.g. bed leveling for 5 minutes) and in maybe 1 out of 10 I have to invest a bit more time for leveling or unclogging the nozzle. But even all that is less than 30 minutes.

Fixing the printer is nothing that I enjoy but using it is so handy that it definitely makes up for the small hassle here and there.
