I really wanted to love this oven. It takes FOREVER to pre-heat and the amount of heat that escapes is ridiculous. I had ribs cooking for 2 hours and it got so hot in the kitchen that the temp in the house got up to 84!  My family was miserable.  I wish I had read the reviews before purchasing. My husband really wanted it for it’s features-I would have talked him into NOT getting this oven. I do like the non-stick racks but they are not worth the heat emission
