Well, I've only used it a couple of times for meals I would have otherwise made in the oven. Once I used the speedcook option for baked beans... I didn't have time to do them in the oven so I put them in the microwave and used the convection/ microwave speed cook combo. It didn't turn out quite as well in the oven but it was still pretty good. The bacon on top crisped up, though not as evenly as it would have in the oven, and the beans were still a little more soupy than they would have been in the oven. I did use the convection bake for some meatballs that I normally do in the oven. Those turned out great. They browned on top just like they would have in the oven.
All in all, I'm really pleased with it so far. I haven't tried baking pies cookies or cakes in it yet. But I think it'll do the job all right.
