I've had a single tray air fryer for a couple of years and it was such a pain when i would have to make two whole chickens, I would have to do them one at a time.  I saw the Ninja Foodi and wanted it.  My husband bought it for me as an early Christmas gift.  I did two whole chickens the other night and they came out awesome.  I can't wait to cook whole meals in it and them done at the same time.
