I had another air fryer with the seperateble basket and while it's a good idea in theory it limits the cooking space in the air fryer.  This has this crisper tray with the rubber feet on the bottom which I thought was a great idea, gives you the space to cook and it stays in place when empting the basket.  The rubber feet on the crisper tray make it so the tray doesnt fall out when you empty it so it doesnt burn your hands. great product.
