backinit We have had an air fryer for a couple years now. Very basic, has knobs no digital buttons. Adding a little cooking spray makes a world of difference. My wife made some tater tots in our air fryer last night and they came out just as crispy as the deep fryer with just a few sprays of cooking spray. We cook "Checkers" seasoned french frys in it without any oil and they turn out great as well.
It really shines when it comes to reheating foods. I think the easy of clean up makes regular/basket air fryers better then the air fryer/toaster combo.
