I just received my Ninja Double Stack Air Fryer. So far I love it. I wanted a dual basket air fryer but the design of the models prior to this one were too wide to fit on my countertop. Bravo to Ninja for coming up with a stackable solution that definitely works for me. I live in a motor home and have a very small kitchen with limited counter space. It fits perfectly in a corner that provides adequate ventilation and I have enough counter space in front of the machine to easily pull out the baskets. I am impressed with the cooking functions and cleanup so far but am still in the testing phase. Some people who bought the UK model have complained about uneven cooking and extended cooking times. I have not had that problem yet. Anyway, I don't regret the investment and am a happy camper
