Like @GasPanic I'm underwhelmed by my airfryer experience. As someone living alone I thought it would be ideal to save putting the oven on for a small amount of food. And yes, once a week, or more often once a fortnight, it's useful for that. I can roast a bit of chicken, or do some fast roast new potatoes, or re-heat a pie.
I have a Ninja 300 which is fine, but it's a total pain to get stuff out of the deep drawers.
But it turns out that I just don't eat the kinds of foods that an air fryer is great for. And some of the pictures I've seen of people trying to cook stuff in their airfryer that NEEDS an oven, or that is better done on the hob or slow cooked, are pretty disgusting looking. Why make a four inch square cake instead of a real one? Especially when it doesn't even rise evenly? Loads of things come out unevenly browned, and I seem to have to pay more attention to the air fryer (regularly shaking or turning stuff) than I ever did cooking the same things in the oven.
Yes, it's really handy on the aforementioned occasions, but I don't understand the airfryer obesession, and how anyone can cook for a family in them.
