The ninja rapid cooker and air fryer is awesome. It is so easy to use. There is a booklet included in the box that explains it and also has some recipes. So far ive used it only as an air fryer and I love it. I bought some cooking sheets that I use when air frying sth, because this way its so much easier to clean it. To use it as a rapid cooker you just flip the switch to the right setting and you are set.
