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.

    I just use it one time and is already making weird noises and there is a weird smell as well. I have other ninja products with no problems. Unfortunately this oven didn’t meet my expectations

    I am obsessed with this oven!! My previous one was a pampered chef one and I loved it but once it broke I had to research and found this one. I love how large the cooking space is and I love how you can cook completely different foods and it all comes out at the same time! I HIGHLY RECOMMEND!!!!!!

  4. Very high quality air fryer, love the dual cooking zones and the stainless steel (not non-stick)

    Pre-heats quickly. Controls are intuitive. Dials and buttons feel high quality. Air fry fan is pretty loud but delivers even and consistent results.
