I have a very small kitchen and this does so much that I can get rid of several items and have this one appliance. I am so pleased for this product because it can grill, smoke, bake dehydrate, and much more. I have not tried out all the features yet, but I have made fries, pizza, and a whole chicken, and everything turned out great and tasted great.  It comes with a cookbook, which I needed because I'm learning. You can also scan the QR code which is all you need to know about this grill. I love this grill and  would totally recommend it. I read several places that the doors shut, I have not had any problem with the door closing on its own. I can not say enough about it,  overall I think its the best. I wanted to add the food turns out beautiful and tasty.
