I can fit a baking dish in it so I can use it for many of the things I might want to bake in my oven (lasagna, casserole, small batch of cookies/muffins) but don't want to heat the entire oven for. It fits a standard frozen pizza, I've occasionally baked bread or rolls in it. One of my most frequent uses would be the broiler setting where I just want to quickly brown the top or melt cheese onto something.

One of the drawbacks of my current air fryer is that the fan blows so hard I have to make sure that what I put in there is heavy and secure enough not to get blown around. My son was heating something and put a piece of cheese on it to melt. The cheese was definitely NOT where it was supposed to be when it melted.
