Well, I don't have it yet, but I have been looking into this somewhat obsessively and have decided on a Breville Smart Oven Air Fryer Pro.
I had a Gourmia and the directions said it is normal to smell the weird plastic smell the first time you use it, and that it should go away. It never went away after using it probably 50 times. I gave that air fryer away on my FB Buy Nothing group.
All of that said, the Breville I am recommending is probably overkill just for french fries.
