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.

    Top Notch, but usually only lasts about two years. I am on my third one.

    I bought this Ninja because my other went out after 2 years of failure use. I heavily use the air fryer to make many of my meals. The temperature and functionality are the same. The temp gauge is inaccurate to say the least. Heat escapes from the unit worse than the previous model. Needless to say, I returned the unit and bought an entirely different brand.

    Oh, and it’s noisy. It has a normal sound and then out of no where it sounds like a drone or small plane taking off.

  4. One of the best purchases I've ever made

    My full gas oven very rarely gets used now. This thing does everything amazingly while keeping the kitchen cool. It is huge and all the accessories are great.

    Chef Chris Young did a review on this, and he makes a small mistake saying that it can’t be used for baking without the convection fan. The reheat function can be used for baking if you don’t want to use the convection fan!

    Like all counter top ovens and toaster ovens, this thing is not particularly easy to DEEP clean, but it is very easy to spot clean any issues as long as you do it right away. For example, if there is splatter on the glass or the crumb tray, just take care of it before it sets. As for getting crumbs and into the deeper parts of the oven, you will have to dedicate some time to do it, and trust me, the sooner the better. Don’t let the oven get too dirty. Take care of future you by cleaning regularly.

    A small tip is to make sure that you get a brush to clean the air frying basket. It will shred your sponges.

    I cannot overstate how much I love this oven.

    This our 2nd oven! Moved the original one to our RV! My only advice is to clean it after every cook. Not easy to clean once grease splatter gets baked on.

    Our apartment doesn’t have an oven and this has been a LIFE SAVER. It preheats so fast and cooks very evenly. I’d recommend rotating cookies, but all my cakes have come out great. My husband loves using it to make fried chicken and bagels—it never misses.

    Good Air fryer, works real well. Fries a lot of things. If you need to deep fry some important documents this things got you.

    This thing is amazing. I use it almost everyday. It cooks so much food at high temperatures and automatically shuts off. I’m very happy with it

    I love the convenience of the oven. The inside and the heating units get really greasy though and I’m still trying to figure out how to clean it. All in all I would recommend the oven but be leary of keeping it clean.
