ive never used them to replace frying because i never fried anything. it really becomes more of a decent quality oven, if you have a crappy normal oven buying a small compact electric air fryer with a big fan for circluation will make cooking easier - quicker preheat, some foods cook quicker, things cook more evenly, able to use higher consistent temps
i actually got a countertop oven instead - which has an "airfry" mode. it has 3 racks, a big ass fan in the back, two heating elements, and essentially does the same as an airfryer for me
