I LOVE my air fryer. I have slowly upgraded to bigger and bigger models.
The Power XL, copper chef brand is probably my favorite.
Started with the egg shaped fryer, good but limited capacity depending on what you are cooking and for how many people.
Then got the oven type with the slide in trays and rotisserie. This is nice but need to switch the trays of food around to cook even, don't overcrowd, excellent results.
Then bought the type with a lift top lid, to grill, bake, fry, air fry and has a much bigger basket and capacity.
Hardly use my large oven any more. Evo oil sprayer is a must.
'Really depends on the amt and type of food you cook. I use for everything from veggies, potatoes, fish, chicken, to rewarming pizza.
