So far this is performing as expected, namely, perfectly.  Very impressed by the shipping box which was so carefully thought out, the journey from the East Coast to the West coast was without any damage at all.  Followed the set-up instructions, to preheat to burn off manufacturing oils, used the broiler pan a few times, used the convection oven, all work well, and especially like the power-burner for boiling pasta water. 
It looks terrific, and we are very happy.   We are religiously cleaning it, just with warm water and mild dishsoap and a soft rag.
