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.

    This is the best toaster oven, l’ve had other high end toaster ovens that weren’t very good. Ninja did a good job with this oven, it cooks so even and I like at the feature that shows it’s hot when done using it

    I gave this a 4 star because toasting is hit or miss. Some breads toast ok others not well at all. Everything else works well.

  5. Best Oven Ever!

    This was the best investment ever in my kitchen! I don’t need to wait for big ovens to heat up or clean up messy ovens. This heats up quickly and cooks as good if not better than my oven! Easy to wipe clean also! Lifesaver!

  6. A mixed experience with this countertop oven & air fryer

    Verified purchase

    I wanted to love this air fryer toaster oven, but two major issues have significantly impacted my experience. Here’s an honest breakdown of the concerns:

    1. Noise Level: Convection Fan Issues

    When using the whole roast function, the noise level was shockingly high. The convection fan sounds like a tractor, making it impossible to ignore in my apartment. What’s worse, the housing and door resonate with the fan, creating an annoying rumble. I found that touching or holding the unit temporarily reduced the low-frequency noise, but the high-pitched sound persisted. I’m unsure if this is a defect in my unit or a design flaw, but it’s incredibly frustrating.

    2. Surface Gets Dangerously Hot

    The exterior surface becomes alarmingly hot during operation:

    The upper door frame (just below the handle) measured 125°C (257°F).
    The front edge of the housing reached 90°C (194°F).
    These areas are easy to touch accidentally, posing a serious burn risk. For a countertop appliance, this level of heat on accessible surfaces is unacceptable and potentially dangerous.

    3. Clearance and Stability Concerns

    The clearance between the unit and my kitchen cabinet was only 5 inches, which feels far too close and raises concerns about a potential fire hazard.
    Additionally, when opening the door, the oven slipped on my quartz countertop—and my countertop wasn’t greasy or wet. If there’s hot food inside, this could be a major safety risk.

    While the oven offers a lot of cooking features, these safety and usability concerns make it hard to recommend without reservations. I hope the manufacturer addresses these issues, as they seriously affect both the convenience and safety of the product.

    If noise and heat aren’t deal-breakers for you, this oven might still be worth considering for its functionality. For me, however, these drawbacks outweigh the benefits.

  7. Cannot Air-fry in the top section.

    The top section does not allow Air-Frying. This is unfortunate and not what I expected. I often air-fry chicken nuggets or tatter-tots, while desiring to Bake or Broil bigger dishes at the same time. I cannot because air-fry is only available in the lower section, which is bigger. The dishes that I would rather Bake or Broil are often too tall to fit in the upper section.

  8. A lot smaller than I thought.

    Nice oven, but I was hoping for a little bigger one by ordering the XL. Top oven is very small and shallow and bottom oven can only cook small chickens or roasts. Overall, the oven is very nice tho, just not what I thought it would be. I haven’t cooked with it yet so can add to this review once I do.
