I had the issue with the x-axis too, but the restart method is an easy fix. As for the sticking, I use buildtak. It’s super cheap, and amazing! No tape, no glue, reusable - it is really amazing. Buy a few, in case you hack into it with a knife. My printer started dropping ball bearing from the x-axis linear bearing, so I’m returning it for a new one. As for quality, I get amazing prints, right out of the package. If you level the bed and are still getting garbage, return it ASAP.
