I read all the reviews and had great hopes for this item. I have been disappointed and it doesn't pop popcorn well at all. Convection oven works, and so does the grill but is not easy to clean if you are doing steaks or burgers (items that spatter). The microwave does behave ok, but you need to adjust times and always use a dish, since on the metal tray alone it takes much longer - a microwave thing, I think. It's useful enough to keep, but I would not order the same thing as a replacement. The compu functions I have tried don't seem to match my needs and it's complicated to figure out which option to use - constantly looking at the manual for reference. Defrost works pretty well. If I can figure out how to get popcorn popped, I might give it a 4 star.
