Ninja Prestige Smart XL with Pro Cook System 10 in 1 Digital Countertop Convection Toaster Oven, Air Fry, Air Roast, Broil and Bake, Thermometer, 1800 Watts, Stainless Steel, DT551

This is now my fourth Ninja Smart XL oven since these first came out, and that alone should say a lot about how much I use them. With almost daily use, my previous units lasted around 3–4 years each, which I think is pretty reasonable considering how often they run in my kitchen. Honestly, I rarely use my full-size kitchen oven anymore. This has become my go-to for everything from reheating leftovers to cooking full meals, baking, roasting, air frying, and making things extra crispy much faster than a traditional oven. The updated version looks great with the stainless steel finish wrapping around the entire unit, giving it a much cleaner and more premium appearance on the countertop. One thing I really appreciated is that all of my older trays, racks, and accessories still fit perfectly, so upgrading was simple. Performance on this newer model also seems improved. It heats more evenly, cooks faster, and definitely gets food crispier compared to my older versions. The controls are easy to use, it preheats quickly, and the overall cooking results have been excellent. If you cook often and want to avoid constantly heating up a large oven, this is an excellent countertop replacement. I’ve been very happy with the updates in this newest version.

Wow, I just love this fryer/oven. The controls are easy to use, and the 90-second preheat feature is a great added touch. Cooking pizza has been excellent, heating speed and evenness is also excellent. This unit fits under the standard house build cabinet height. The high temperature of 450F should be enough for most users.

This is the coolest appliance I've ever owned and I have a lot of Ninja products. This is about the size of a residential microwave, is more energy efficient that a residential Oven, even though it cooks faster than an oven, while also having several other functions that work flawlessly. My favorite part is how easy it is to clean the oven & inserts. Money well spent!

I LOVE this so much! Took a little time to adjust to temps and timing but this is the most popular item in the kitchen.

Big oven cooks even and can handle larger items like hams or turkeys. We like the way it cooks, but the fan is loud. It spins up to speed and sounds like a DC-9 getting ready to take off. Cooks great but a little on the noisy side. (Maybe not as loud as a DC-9 those were some noisy airplanes!)

You can't smelt gold, but you just want to roast/fry/bake it's outstanding. We use this oven multiple times per day and it works great. We hardly ever turn the oven on our stove, except when we need extra capacity or a larger oven size (like at Thanksgiving). My only complaint about this oven is that it's got one fragile bundle of wires that run from the oven body to the door, which are connected to the control panel on the door handle. Over 12-18 months it will fail. We're on our third oven of this type. The good news is, the warranty is substantial and Ninja is good about replacing the oven quickly when it fails - of course you have to cut the power cord off and prove you did so before they ship the replacement, so it would be tough to scam them and just re-splice the control cable and the power cable. Honestly, we love this oven and will always have one on our counter.

I love the oven but no amount of 'wiping it out once cooled' will remove the baked on grease. I tried their support but the AI chatbot kept talking in circles and linking me to information I already read in the manual. It says not to use harsh cleaners but doesn't actually give any options of what you can use to clean the interior and fan. It not only looks bad but the fan is already starting to make off noises because there's some getting in there too. It would be a 5 star if there was a way to actually clean it. I shouldn't have to go digging for that info and I definitely shouldn't come up with nothing for a product that was $400. Ridiculous.

This won't be anything close to the best, all encompassing review you'll read on this product. I'll simply give you my thoughts from the position of a husband and father who have been sold by my wife and kids to get something like this. We are fairly healthy eaters and this air fryer movement seems to be a good idea for a variety of foods. Anyway, I rarely cook anything processed and Frozen but now and again it happens. To get to the meat and potatoes of this unit, for someone like me who mainly what's with cast iron and an oven, this ninja air fryer comes across initially as very user friendly. I'm not saying you won't mess something up but it seems very intuitive with the layout of the buttons and the information the readouts give you. As you'll see in the picture, I decided to really test this on my first cook by putting two different foods in the same cycle. Luckily fish sticks and Frozen Pizza are generally in the same cook time and temperature window. From Stone cold, 10 minutes at 400° was just about perfect although it probably could have used an extra minute. The oven suggested 15 minutes but I think that would have started burning. The other thing I like is that this comes with plenty of accessories and I can't think of anything else I would need to buy for what we cook here. It also comes with a wizzy thermometer. The instructions are fairly clear for the most part but you might have to do some homework if you were going to do actual from scratch recipes. Until you learn the strength I would definitely check up on suggested time and maybe drop a bit. You can always put the food back in to cook further.

Es muy bonito, muy buena construcción y se siente muy profesional además muy facil de entender los controles, el abanico no me párese tan ruidoso como indican otras reseñas, el tamaño externo es como mi actual cuisinart toa65 pero la camara de cocción si es mucho más grande la del horno ninja, aún no lo pruebo con alguna receta ya que recomiendan recalentar el horno y charolas antes de preparar alimentos y es lo que hago en este momento tal ves otro día probaré con lasaña o pan y volveré para contar la experiencia de este horno ninja dt551 vs mi antiguo horno cuisinart toa65 pero de momento me siento muy contento con mi nuevo horno ya que le da un toque de modernidad a mi cocina
