This oven is absolutely wonderful.  As a microwave, it is fantastic  I love the "sensing" mode as everything I've reheated has come out perfect in every way.  I've used the rack and metal pan to cook 2 items at once. The item cooking on the rack came out perfect.  The egg product on the metal pan turntable required an additional 15 minutes to be cooked properly.  I'm not sure why, but will definitely be experimenting with the various functions it offers.  Thus far, the microwave reheating feature is a hit with our family.
