I received this 3 days ago - put together the same day.  The bottom sheet metal portion wasn't sturdy and three screw holes didn't match up.  I had to drill extra holes to get the screws into place.  After some manhandling, I got the base setup.  One thing that didn't align completely was the door doesn't close all the way.  

The top is heavy and sturdy but had some issues getting the last 4 screws in because the base wasn't a true circle due to the unmatching screw holes.  But, I got it screwed in, plug in the 20lb beutain can and the fire pit worked like a charm.

This took me and a little helper about 2 hours to put together
