I had seen a few positive reviews on this machine, so I pulled the trigger.
It's early days yet, but assembly was very straightforward and I ran the levelling routine, which reported quite acceptable results. Then, without any fiddling AT ALL, I printed the cat model that came on the included SD card using the white PLA filament supplied. I then tried printing with black PLA I have had sitting around for a couple of years - in the open. I expected problems, but it printed fine and my first inspection didn't notice anything ... but then I am a novice here. There was a tiny amount of stringing that was a wispy as a spider web on both - but that disappeared as soon as I touched it.
Bottom line - IMHO - a happy out of the box experience.
