It's a nice, sturdy unit!  Looks great and fun to have a fire with far less smoke in our face.  Some drawbacks during assembly.  The steel mesh section was dented in about one inch deep in a 4 inch area and the entire mesh section was out of round by about 2 inches and took a lot of tweeking to fit right!  Be extra carefull when tightening any bolts as laid out in instructions!  Especially when tightening the first flue pipe!  Their is a large overfit gap and the cast iron will crack or chunk out when tightening.  As it did to me.  I remedied this by adding a large washer on the inside to grab beyond where material was missing!  We've had 3 fires so far!  We'll see how it holds up over time.  This unit is well worth the money.  We like it a lot.
