This Ninja 12-in-1 Smart Double Oven is such a time saver so it''s perfect for busy families. It can cook in 12 different ways and I haven't noticed any crossing of flavors between the two ovens. I can make my family a chicken and vegetable dinner on the bottom while cookies are baking on the top and come out right when we want them. It doesn't take up too much room on my counter and everyone that has seen it asks me so many questions about it and they are always impressed. I find it pretty simple to cleans and I like all the accessories that came with it. Such a great device!
