Ninja Foodi XL Pro Air Oven is great.  It does so many things.  It has two trays with 2 levels of cooking and it seemed like the oven sensed what tray the food was on. Because I had one item on top and the oven said level 3.   It comes with 2 trays, an air fryer tray, and a roasting pan.  The instructions are very easy but I will sit down and read them again just so  I know what this oven can do.  it's quiet and the buttons make sense.  I used both the bake feature and the broil feature so far.  It air frys, air roasts, dehydrates, bakes, toasts, broils, it does everything.  Very easy to use, first you select a function and you can adjust the time and the temperature from there.  The little cookbook is nice too.  Makes me want to try them all.
