This is the best ninja smart oven to have in your kitchen

Great alternative to the oven plus it has an air-fryer.

I liked it until it stopped working after 3 months.

I bought this as a bigger replacement for my air fryer but this is so much more. First off, it heats up to 400 degrees in about 1 minute vs the 10 minutes it takes to warm up so it is a great/efficient alternative to the over. It also holds about 4x the food as our old air fryer. I'm sure this is saving me a ton of money over using the oven. We have also dehydrated bananas in it and it was super easy. I haven't used it for cooking meat yet so I haven't used the thermometer but, hopefully, it works as well as the rest of the unit. I did see several reviews that said it gets super hot. I did notice the top gets hot if you have it on a high temp for a long time. There is a warning on the top about the heat. I cooked garlic bread at 400 degrees last night for 9 minutes and could put my hand on the top immediately after taking the bread out so, at least m unit, doesn't get hotter than I expected. I was worried the counter top might get hot under it but the space under the unit seems to be adequate for allowing plenty of airflow to not get the counter top more than a few degrees warmer than the room.

I bought this a year ago to cook a Thanksgiving turkey after my range stopped working. All the settings work as advertised & the size is perfect. In fact, it was so easy to use and cooked such great meals, I waited a whole year to replace my range. My only complaint, and the reason for the 4-star review, is how difficult the interior is to clean. The operation isn't affected by the splatters, but it looks awful.

This is pretty easy to use with a little learning curve. Definitely go by cooking times in the manual instead of directions on the product. This is a well built product. This was on sale, as well as plus membership deal made this a steal. Outer housing does get pretty warm while using.

In love with this! I have a small kitchen and it is perfect for my needs- cleared up a lot of counter space (it is deep so be prepared) but managed to compact 3 appliances into 1 with multiple uses! Easy to clean and does a great job!

Great air fryer / air oven! I already have cooked french fries with ease and fish, fantastic Christmas present for my wife who loves kitchen "gadgets". This one is a definite winner, easy to use, clean, and will be great for future dinners!

I debated. Then I thought, I will give it a try. Oh my gosh. I am in love! This thing is amazing!! I use it every day. I take videos and send to my sister constantly. I really did not expect it to be this great. The thermometer that comes with it and the setting to just set the temp it needs to reach is perfect every time! This is so easy to use and works great for my family. I have been using it for about 2 months and no issues. just a lot of food and good times. I have had no issues. The air fry mode does get a little noisy like most do. But over all with the performance of the system as a whole I’m not bothered with a little noise when I do use the air fry mode. I love this and cannot see my kitchen without it anymore. I would definitely purchase again.

Our oven was acting up and the people we rent from were being reluctant to replace our oven. So we were in the market for a toaster oven/air fryer that was a bit on the larger side like this one. In the weeks waiting for the landlords to order a replacement part, we got this Ninja and we've baked cakes, cookies, pizzas, all kinds of things. I don't want to get it super messy and cook in the basket and all that, but I believe this would cook basically anything you put in it. It does get up to temp pretty fast. I feel like it's pretty efficient in getting a crisp food as opposed to having soggy convenience meals from the freezer. Certain snacks are just better crispy. It's a mini oven, but there's plenty of room in there, several racks you can remove as necessary.

I bought this to replace my older ninja oven that i had for a long time. It was basically just the older version of this new model but it still worked. It was just so dirty and i could not get it clean. It did start having an issue toasting only one side of the bread. So i got the new one at a great sale price. Hopefully this one lasts as long as the last one. We use it everyday. Its so much easier and fast than using a regular oven. This one seems to air fry better also. I love ninja/shark and have many of their products from kitchen to vacuum and cqrpet cleaners.

This Ninja Foodi is amazing. Got it on sale. Easy to use, heats up quickly, the fan isn't super loud and it cooks food great.

This is my first air fryer, so I cannot compare this to how other air fryers work. I do have a convection oven, so I am a bit familiar with the concept. It comes with two booklets giving clear instructions for its use as well as a variety of recipe ideas for using the unit. I like the baking pans and roasting insert as well as the wire basket it comes with, which make it possible to cook several different foods on different rack levels at the same time. This also allows putting a baking sheet below the wire basket to catch any potential droppings from the food being air fried in the upper basket - making clean up a breeze. The thermometer is great and easy to use, and has a very handy magnetic storage device to keep it on the side of the unit when not in use. It quickly preheats, comes up to heat, and cooks the food without heating up the kitchen like our convection oven does. Of course, this is due to the size of this counter-top unit, but considering it is very much like a mini-sized convection oven, it is making meal prep much easier when the quantity of food doesn't require using the regular oven. I haven't used all of its features yet, but expect them to be as easy and rewarding as the ones I have used. The food has been great. I particularly like the way the french fries are turning out compared to my simply baking them on a cookie sheet in my oven in the past. Although I purchased this on a "door-crasher" sales event with $200 dollars off, I think it would be worth the value at the regular price now with how easy it is to use and all the features it has, notwithstanding that it takes up a little bit of counter space the smaller, but less versatile, air fryers out there. Plus, the brand is one we have always had great success with.

We are overall very pleased with the Ninja DT251. This is our first Ninja product, and we were on the hunt for the best air fryer on the market. After reading a lot of positive reviews, we decided to give this one a try, and we’re happy we did. The large rear fan is particularly impressive—it really enhances the air frying capabilities and ensures crisp results every time. So far, we’ve used almost all of the functions on this Ninja, from air frying wings to toasting bread to reheating pizza, and we’ve been consistently impressed with the results. It cooks evenly, and the convenience of having multiple cooking functions is a major plus. We did run into a small issue about a month in when the fan started making a loud noise. We contacted Ninja support, and they were fantastic—they immediately heard the issue and replaced the unit without hesitation. This leads me to believe they may be aware of this issue, but their customer service was top-notch, and we had no problems with the exchange. All in all, this is a great product with solid performance. We’ve tried other air fryers, and so far, nothing has compared to the Ninja DT251. Even as fans of Breville products, we haven't found anything from them that competes quite as well in this category.

So far it's really great. It's awesome that it heats up so quickly and it really does cook evenly. I've read some reviews that say it's loud, I feel it's quieter than 2 other air fryers I've used. The only bad thing is that the sides get dirty and they're not easy to clean. Other than that, great product, works, well, and we use it everyday. It is a little pricey, but for what it offers, I think it's great. It can also replace the need to use your oven for smaller things.

I really like this Ninja Foodi 10-in-1 oven, it is easy to use, has a time and a temp button which makes it very easy. I don't need a machine to tell me how to cook what I am cooking. Love the drop down door, compared to the spring loaded double doors on some air fryers that spring back and burn your arm. Very happy with the purchase and would highly recommend it.

Our old Breville oven finally died and decided to give this Ninja a try....was pleasantly surprised. Easy to use and food cook/taste quality has been better than expected. Used the whole roast function for a whole chicken as the first use and it was perfectly done thanks to the attached thermometer. A keeper so far.

This Ninja product is simply fantastic. It has such versatility and performs well as an air fryer, toaster and oven. These are the only functions I've used so far and I expect the others to work just as well. To me it just seems precision. It has taken the place of my full-sized oven for most tasks.

Best air fryer to Roast a 13 pound Full Turkey. Did the work my Turkey was cooked perfectly juicy .

I bought the oven with a very good discount. It is very nice for the paid price. The only thing I don't like is, sometimes something is vibrating when the ventilator is running. But overall, for the price, is a verry good, nice looking oven. I used almost daily.
