Since day 1 of having this product, it has replaced our separate microwave, griller, convection oven. We like to bake our own home-made pizza & this great oven does its best performance. It saved us a lot of space on our countertop because it's an all-in-one oven. We roasted a whole roaster chicken, and the result, crispy on the outside and juicy in the inside!!! And just like our other Samsung appliances (yes, we had a refrigerator, washing machine & dryer), it's as quiet as compared to our old microwave (or even I bet with the other brands).
