I just used my air fryer for the first time and love it. I used it to cook dumplings that I usually cook in my wok. They came out crispy on the edges and moist in the middle. Just how I would fry them. 
I can't wait to use it again. You set the temperature and then the timer. It's that easy. 
There is a recipe booklet that comes with it to give you lots of ideas. I would recommend this product.
