I love everything about this double wall oven except one thing! The air fryer is so good that I bought a 2nd air fryer rack. However, if are making wings, bake them at 375 for 15-20 minutes. Then pull them off a pan and on the air fryer rack and air fry for another 10-15 minutes. This will avoid being smoked out of the house. 
However, I really dislike that the temps are in 25° increments. I have a cookie recipe that does best at 365°. I love to bake and have had to spend time tweaking recipes and cook times. 350° to 375° is a massive jump in heat. Which is even more important when ovens can be hotter or colder than what it is set to. Up to 25° or more depending on the oven.
