I have a Breville and I love it. This is similar to the one I have: https://www.williams-sonoma.com/products/breville-smart-oven-air/
I can’t think of the last time I used my “big” oven. Food cooks quickly. Toasts, air fryer, settings for baking, broil, bagels, pizza, it will dehydrate fruits, etc. - proofs dough for bread - I’m so happy we got one. I have not noticed the problem with the exterior overheating or the space getting too warm. My kitchen is small with limited counter space, but I use this more than any other piece of kitchen equipment.
