I have owned this Ninja for a few weeks and love it!!!  Grilling is as good as outdoors, air fryer so far has created amazing fries and veggies.  Honestly you don't need an oven with this Ninja - Grill, Road, Air Fry & Dehydrate.  I also purchased this to encourage my college graduate to start cooking & it is working.  This in a wonderful cooking tool and fast - can't recommend it enough!
