Assembly was easy, all the parts and instructions were easy to follow and parts fit easily.  Haven't tried unit yet, but expect good results. Allen wrench was included for assembly.  As others have mentioned, optional wind screen wasn't included or offered, so we ordered this through Wayfair thru another source.  In deciding on a windscreen, understand that you need approx. 2.5" clearance on all sides beyond the fire pit perimeter.  I am wondering if 
rubber feet are needed to hold it in place on the table.  Wind guard hasn't arrived yet so don't know if rubber feet are included. Great feature is the under unit propane tank placement that easily rolls in and out. Adjustable flame is also a positive.
