Update after 6 months. I have changed my rating because of the quality of the material used for the inside of the door and the floor of the oven (see Photograph). I have noticed that these areas first showed signs of pitting followed by rusting. the deterioration seems to be getting worse so I am not certain how long that this oven will continue to be useable. the door material reminds me of what happens when the surface zinc on galvanized iron is compromised and rusting occurs. I purchased this from ninjaoutlets.com Warehouse as refurbished and I have no regrets. This is my 5th countertop toaster oven which I bought for it's air fryer capabilities. This oven is money well spent Pros. It does everything my larger oven does in addition to toasting. It's compact and doesn't take up a lot of counter top space. With two shelves I am able to cook two different dishes at the same time. It comfortably fits 2 quater sizes baking/cookie sheets. It's a convection oven, which allows even browning/ cooking on all sides, cooks at a lower temperature and is faster than conventional ovens.. it can hold a chicken for roasting that can easily feed my family of 4. It's air fryer that can cook several servings of fries, however I am still undecided on the quality of the fries produced. It certainly not as good as regular feet fat frying fries, but I have no reference as to quality of other dedicated air fryer performance, that being said, the quality isn't bad, fries tend to be a bit dry. Cons. My major issue is the difficulty in cleaning. I wish it had a self cleaning interior or the removable back that the sp1o1 has to facilitate cleaning. I just spent several hours cleaning up the splatter from my barbecue ribs. Next time I cook barbecue ribs I will use my conventional oven as cleaning is so much easier
