The main electronic controller failed after less than one week.  It has since been replaced (three week lead time) and working well since.  The upper oven reaches cooking temp very quickly and stove top burners are very hot; maintaining a simmer (without going back to a boil) is challenging.  Also, be aware that this unit ships from factory configured for natural gas.  I live in the country and it required extra effort to schedule a technician to switch fittings for propane.  The unit does ship with the needed fittings.  And, to be fair, any other natural gas unit would need the same service.
