I had wanted air fryer, to go in camper for a while. I was trying to find MW, convection oven, air fryer combo. I then ran across outside pellet grill, that had air fryer. Long story short, I've been using heck out it. Replaced gas BBQ grill, and does extra duty with options. I did have issues but on convection fan falling off. I bought security torx bit and new nut. I debated getting pro vs compact model. I got compact model, I think if you have room Pro size, isn't that much larger.
Here's a much better review, than I can do. It's most useful for uncooked sausages, hamburger patties, for a quick meal. The air fryer makes pretty good chicken and shrimp, I haven't done fish on it yet. Chuck roast, turned out better than brisket, but brisket didn't have fat cap.
