Ninja Prestige Smart XL Pro Cook System, 10-in-1, 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.

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!

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.

Big. Beautiful. Heats super fast as advertised. Great, well made accessories too. BUT! The timer starts as soon as set temperature is reached. So you must be standing there ready to add food. Should have timer start once the door has been opened then closed. Simple, Right?? Come on Ninja, Duh!!

Absolutely love this thing! It bakes! It broils! It airfrys! It reheats whatever can fit inside of it & if it could somehow fold the laundry, it would be perfect!

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.

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.

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.

Me gusta, de buen tamaño, sirve para hornear , pues tiene resistencias arriba y abajo, por lo mismo hornea los panes por dentro y por fuera sin necesidad de voltearlos.Asar, dorar, freir, deshidratar, tostar, recalentar, etc. lo recomiendo altamente 👍🏼

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
