Highlights

FlexDoor™ Dual Oven Design The innovative FlexDoor™ creates two independent ovens in one compact footprint, allowing you to access just the top for quick snacks or open the full door to cook two complete meals at different temperatures and settings simultaneously.
Smart Finish™ with DualZone™ Technology Eliminate back-to-back cooking by syncing both independent ovens to finish at the same time, even if they require different cooking functions, temperatures, or durations.
FlavorSeal Technology Designed with two separate cooking environments, FlavorSeal technology prevents smells and flavors from transferring between the upper and lower ovens, ensuring your main course and dessert stay distinct.
12-in-1 Versatile Functionality This all-in-one appliance offers 12 versatile programs including Air Fry, Convection Bake, Whole Roast, Air Roast, Bake, Broil, Pizza, Toast, Bagel, Reheat, Keep Warm, and Dehydrate.
XL Family-Sized Capacity The spacious interior is designed for large families, fitting up to 6 lbs of wings, a 4.5-lb whole chicken, two 12-inch pizzas, or full sheet pan meals across its two cooking zones.

Pros & Cons

Pros

  • Dual-Zone Versatility: The independent top and bottom ovens allow users to cook two different dishes at different temperatures and settings at the same time, effectively replacing multiple appliances like toasters and air fryers.
  • Smart Finish Technology: The Smart Finish feature is a major highlight, automatically synchronizing the cooking times of both ovens so that different foods are ready to be served at the exact same moment.
  • Fast Preheating and Cooking: Reviewers frequently note that the unit preheats in just a few minutes and cooks food significantly faster than traditional full-sized ovens, making it highly efficient for daily meal prep.

Cons

  • Difficult to Clean: The interior lacks a non-stick coating, making it tough to scrub, and the downward-opening door design allows crumbs and grease to fall into the hinges and crevices.
  • Inconsistent Toasting: Many users report that the toast and bagel settings are too powerful, often burning the edges of bread or producing 'nuclear' heat even on the lowest shade settings.
  • Bulky Size and Hot Exterior: The appliance takes up substantial counter space and is quite heavy; additionally, the exterior surfaces become dangerously hot during operation, posing a potential burn risk.

    Family of 4 and this has been excellent for us. I’m totally happy with this. So far easy to clean. No issues whatsoever! Which is great to say! I’ve been impressed with Ninja products due to durability and quality and that’s what I think about this product as well. We’re actually using daily right now due to being in a extended stay hotel during house renovations and we needed something to cook on/with/ after research, bought due to being large and options are perfect. It’s been getting lots of use! No problems which is exactly why I bought this one!

  6. Rust!!!

    We’ve had this oven for only six months, and the condition of the interior is unacceptable. We use it almost daily and follow the cleaning instructions exactly as recommended, but the surface has started to rust so badly that it looks like it’s made from the cheapest possible metal. High-quality steel does not rust like this.
    There is also a white residue that does not go away no matter how much you wipe it. At this point, I’m seriously concerned about the safety of using this oven – no appliance should look like this after such a short period of time.
    This is extremely disappointing, and honestly, it feels like it’s time to switch back to Breville.

    I love this oven! Lots of great features! Preheats and toasts well unlike my previous oven. The feature to end both ovens at the same time is nice.

  8. Use it daily!

    Absolutely love the convenience of this and being able to use both sections at the same time. Even the toast setting makes perfect toast!

    We love the size of this air fryer and all the settings it can do. It’s so much easier than heating the entire oven up for small dishes.

  10. Love it!

    I had an different air fryer and it just wasn’t big enough. The Ninja air fryer and toaster oven is perfect. I can fit a small pizza in it perfectly and it’s totally a great value for the money. And being able to cook two different items at the same time is fantastic.
