I'm a Big Fan of Ninja products.
 I own two Air Fryer and other products from Ninja. Every time I use my air fryer, I wish I had one more button.  Reset button because most of the time I want to finish my cooking with Air Boil.  For me to do that a literally have to turn off my Air fryer, put it back On so I could change to Air boil.
 That's the only downfall, I have to say.
