I have the Ninja® DCT451 12-in-1 Smart Double Oven and I love love love it! It cooks everything so fast and the fact that I can cook 2 separate things at one time is absolutely wonderful! There are 12 different cooking modes. You can toast, bake, broil, keep warm, reheat, convection bake, and you can even dehydrate with it. What more do you want this almost illuminates the regular oven. This is perfect if you don’t want to turn on your big oven and you don’t want to make your house hot. Where has this item? Been all my life? I would definitely recommend you get one for each household.
