I purchased this along with a convection single wall oven and slate French door refrigerator. With my kitchen layout, I can't have two ovens. However, with the Advantium, I can use convection bake and fix a casserole and still cook something else in the big oven. I love that I don't have to preheat and use the big oven just to cook something small!! I'm still getting used to it and I know it does much more than what I've used it for. I would highly recommend this product!
