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.

  1. Great Functionality. Top Element issues tho

    Great functionality. The upper heating element broke after about 7 months, luckily within the warranty period. Ninja sent a complete replacement base unit (less trays, etc.) but I had to pay about $30 shipping. It’s concerning that the element is not serviceable (at least you can’t purchase one). Hoping that the new one doesn’t have the same issue after the warranty runs out, it has the potential to be a costly fix (purchase new unit).

  2. Great for Multi-Tasking Meals

    We’re very happy with this purchase. Being able to cook two items at different temperatures and settings has made meal prep so much easier. The bottom section is roomy enough to handle a variety of dishes. We use it as our dedicated gluten-free cooking device, and it’s been perfect for keeping meals safe and separate.

    Here’s the thing. This air fryer works great. Cooks everything perfect. But it’s impossible to keep clean. Everytime i pull out the rack to flip anything, all the juices drip all on the glass window. Also the crumb fall all over the counter. Poorly designed.

  10. Defective oven? Too noisy

    Verified purchase
    T. Dotson June 5, 2025
    Review source: Amazon

    Received the oven in a beat up box. Appears to be new but probably a return. I read some of the reviews but didn’t see anyone talking about the noise. It is noisy when operating but we can live with that. However, what we can’t live with is the noise it makes after it’s done cooking and cooling down. At first we thought it was a noisy fan, and that’s where the noise is coming from to cool down the oven. But then we noticed the fan on the side was not blowing air, just making a strange noise, so maybe the fan is stuck and not turning. Not a normal noise.. I suspect Amazon got a defective oven on return and decided to try and resell it. If that’s true, that’s a shame. We have to repack and return the oven now. We liked everything about it but we can’t live with that noise.
