I have one, and I do like it. I don't use it *that* often, but I like having it. I use it for basically anything that can be cooked in the oven, especially on holidays/special occasions when we're having a meal with multiple different dishes/sides, and the oven is being used for something else. And mine has a "keep warm" setting so you can just leave something in there and keep it warm while other things are still cooking in the oven/on the stovetop/whatever.

Or if I'm just cooking for myself and I don't feel like dealing with the oven (the air fryer heats up much quicker), especially in the summer when I don't want to heat the entire kitchen.

It's also really good for any sort of fried frozen food that would be sold in the "appetizer" section of the grocery store (like fries, breaded cheese sticks, etc.) because it's somewhat better than the oven and *way* better than the microwave at keeping them crispy.

I know you can apparently make cakes and desserts and all sorts of other things with it, but I haven't tried that yet. I might need to, though.
