Finally received the unit after a 3 month wait, but so far it was worth it.  I've been using it for a month now and love how quickly it heats pots and pans; and how easy it is to keep clean. My only disappointment was that I hadn't realized the 5th burner was just a warming burner.  I had hoped it was a regular radiant burner that could be used for the few aluminum pans that I still have.  Don't think anyone else does this either. - a shame.
