Personally the return on the air fryer for me is a direct result of it being smaller. For most things my larger kitchen oven needs time to preheat. That's an additional step that isn't required when I just want to roast some vegetables / meat or heat some frozen potato products quickly in the air fryer. This time / extra step is well worth cost for me ($20 of fb marketplace).
