This is my second Advantium, and it is better than the first one. I use the speed cook and microwave features daily. The convection oven is a great additional oven for entertaining and holidays. I also use the convection oven alone for smaller jobs, instead of heating up my larger oven. The oven shelves are wide enough and deep enough to accommodate baking sheets and roasting pans. It is a great product, and it's loaded with features for maximum convenience. The cooking sensors are especially useful.
