I am very happy with the performance and versatility of this DZ201C Ninja Air Fryer. I find it easy to program and clean. I love that it allows me to cook in 2 zones.  It is very useful during the hot summer months when I need to cook indoors, but don’t want to heat up the whole kitchen, which happens when cooking in a traditional oven. Also, no preheat required; simply push the start button and it begins to cook according to how you have programmed it.
