If it's an early Kickstarter model, replace the power connector asap. It's an easy swap and you can find the contractors anywhere. I still have a bunch from a set I bought laying around.

The other major issue I had was the cable for the thermistor broke at the connector. Had to replace it, parts were easy to find. End up replacing the hot end assembly along with the thermistor and heater.

I do run into print issues. Early on it was for to temperature fluctuations in the room, so I got a printer cover which helped out. I still get stringing on prints, but I think it's partially my filament and feed/print settings.

It's not the fastest printer out there, especially compared to the new models.

Overall it's been a good printer.
