The Ninja Foodi Never Stick cookware I received is very impressive from the fit, finish, to performance all are triple A.  They appear to be made fairly thick and take a little while to preheat, with that being said they work great on my glass top stove.  The cookware  cooks food evenly and it doesn't stick to the pan.  Clean up is a breeze with the option to throw it in the dishwasher or hand wash.  You can even use metal utensils in these pans.  The cookware seems to be sturdy and well built and should last just fine.
