We own a cheaper one. Cosori not a brand. Like wings and burgers, but take a long time for french fries. All have great flavor. Bad thing it takes up a lot of counter space. If we had space to leave it set out, we would use it much more. You do away with grease. I really like the chicken wings, It take a couple of times to learn how much time, can't rely on the instructions.
I had an air fryer stand along and it took up a lot of space. I upgraded to a microwave oven that is an air fryer and toaster oven. All 3 in one and it works great. Found at a Walmart store in US.
It's just another gimmick to take up valuable space in the kitchen. If you have a conventional oven, toaster oven, and microwave, that's all you need.
