In short, this unit looks amazing on paper but doesn't perform well in any category of cooking except maybe sensor reheat.   I thought this would be the perfect oven for me but not even close unfortunately.  For one, it never actually gets to temperature especially 425F. After preheat, some genius programmed it to turn on the exhaust fan and blow the hot air OUT of the oven.  Everything takes much longer to cook than a regular oven - cinnamon rolls take about 35 minutes,  frozen chicken nuggets take 30 minutes instead of 15, on and on. So the air fry and convect bake modes just suck. Plus that fan that kicks on is LOUD so as this thing takes TWICE as long to cook,  you can't even hear yourself think because of the noise.   Seriously this thing is worthless.  I'd like to return it and just continue using my regular oven which takes less electricity because it takes half the time to actually cook things.
