Highlights

Integrated Pro Cook System Achieve the perfect level of doneness from rare to well-done at the touch of a button using the integrated thermometer and Auto Temp Detect Intelligence, eliminating the need for guesswork.
Smart Surround Convection Features a high-velocity fan and rear heat source that provides up to 10x the convection power of a traditional built-in oven, delivering an all-around crisp without the need to flip or rotate food.
10-in-1 Versatile Functionality A multi-purpose kitchen powerhouse with 10 specialized cooking programs: Air Fry, Whole Roast, Air Roast, Bake, Dehydrate, Pizza, Broil, Toast, Bagel, and Reheat.
XL Family-Sized Capacity The extra-large interior accommodates two 9×9 baking trays, a 12 lb. turkey, or up to 9 slices of toast simultaneously, making it ideal for large family meals and entertaining.
Rapid Preheat and Cooking Saves time in the kitchen with a lightning-fast 90-second oven preheat and cooking speeds up to 30% faster than a standard full-size convection oven.

Pros & Cons

Pros

  • Exceptional Versatility and Performance: The 10-in-1 functionality allows users to air fry, bake, roast, and dehydrate with consistent results, often making traditional ovens obsolete. It features a large interior capacity that can accommodate whole chickens, 13-inch pizzas, or multiple trays of food simultaneously.
  • Rapid Preheat and Cooking Speed: The unit features an incredibly fast preheat time of approximately 90 seconds, which is significantly faster than standard full-sized ovens. This efficiency allows users to start cooking almost immediately and reduces overall meal preparation time.
  • Integrated Smart Thermometer: The Pro Cook System includes a built-in thermometer probe that monitors internal food temperature and automatically shuts off the unit when the target doneness is reached. This feature eliminates guesswork and ensures meats are cooked perfectly and remain juicy.

Cons

  • High Noise and Vibration Levels: A frequent complaint is the excessive noise generated by the convection fan, which some users compare to a jet engine or an airplane. Additionally, several reviewers reported distracting metallic rattling or vibrations during operation.
  • Large Countertop Footprint: The unit is quite bulky and deep, requiring substantial counter space and clearance from walls due to its rear-venting design. Its size may be problematic for smaller kitchens or standard-depth countertops.
  • Challenging to Clean: Maintaining the interior is difficult because grease and food splatters can easily reach the exposed heating elements and the back fan. Users noted that baked-on residue is hard to remove and the crumb tray can be tricky to empty without spilling.

    After our house fire we needed a way to cook while waiting on it to be rebuilt. This has serviced all of our oven needs.

    This Ninja oven was a total lifesaver. It’s fast, easy to use, and cooks food perfectly. When our main oven broke right before Thanksgiving, we roasted a full 20-lb turkey and it came out great. Customer service was excellent and helped save our holiday. Highly recommend.

    So far so good. Bakes well. Air fry very well. Big enough to do a lot in. It does take a lot of counter space. It’s quiet. Easy to use. Has many functions. Heats up quick. Efficient.

  9. The Area behind this unit gets really hot!!

    Charlie Dobson December 21, 2025

    This Ninja Air Fryer looks very nice and they really fill the box with accessories. That said, that’s where the excitement stops. This unit is very big, which most would consider a bonus, however, this unit needs to be more than 6” from the wall and the back sticks way out. It vents out the back so it gets very hot behind it.

    Other folks have mentioned the fan noise. I’ll try to post a video of that. It is really loud and it actually sounds like something is loose when it’s spinning fast.

    I did not cook with it. I just did initial start up. I’ll be returning this unit ASAP.

  10. Happy customer

    We got this thing because my best friend swears by theirs. They were 100% correct! There’s so much room in here, you can prep something for the whole family at the same time. Super simple to use, too. Even the kids have been able to figure it out!
