I have not tested many brands. I own the Cuisinart Convection Toaster Oven AirFryer, which is great for my needs. It is both a toaster oven and an air fryer, so it has multiple uses. It is also fairly small, taking up minimal counter space. Plus, the cooking tray is stainless steel, and not a toxic nonstick material. Things to consider when buying an air fryer: Size - If you have a large family, or do a lot of meal prep, go with a larger air fryer to avoid batch cooking. Overcrowding the air fryer with too much food prevents it from getting crispy. Material - Air fryers typically use nonstick materials to line the interior. Some are more toxic than others. Reviews - Always read reviews to see how it performs. Warranty - Make sure it comes with a warranty in case it is damaged or stops working.
