Our Testing Experience

First Impressions

When I first unpacked the Ninja DT251 Foodi 10-in-1 Smart XL Air Fry Oven, I was impressed by its sleek silver design and solid build. It felt sturdy and well-made. Setting it up was straightforward, and the size (about 13 by 20 inches) fit nicely on my kitchen counter without taking up too much space. I was excited to try out all the different functions, especially the air fry and smart thermometer features. Right away, I noticed the clear digital controls and the included recipe guide, which made it easy to get started even without prior experience.

Daily Use

Using this oven quickly became part of my daily routine. I loved how versatile it was — from toasting bagels in the morning to air frying crispy chicken wings for dinner. The True Surround Convection cooked food faster than my old oven, and everything came out crispy on the outside and juicy inside. I also appreciated the smart cook system; the thermometer took the guesswork out of cooking meats, so I never worried about undercooking or overcooking. Cleanup was easy too, thanks to the six included trays and the non-stick surfaces.

Key Features in Action

The 10-in-1 functions really stood out. Air frying was my favorite — it gave that crispy texture without needing much oil. The smart thermometer was a game changer; I simply set the doneness level, and the oven alerted me when the food was perfectly cooked. The True Surround Convection made a noticeable difference, especially when roasting whole chickens or baking pizzas, as the heat distributed evenly and cooked faster than a regular oven. The included recipe guide was helpful for trying new dishes and making the most of the appliance.

Long-Term Performance

After using the Ninja Foodi Air Fry Oven for several weeks, it has proven to be reliable and consistent. It heats up quickly every time, and the cooking results have remained excellent. Even with frequent use, the trays and interior stayed in good condition without stains or damage. I haven’t faced any issues with the digital controls or thermometer, which still work perfectly. Overall, it’s become an essential kitchen tool that saves me time and helps me cook healthier meals.
