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. My favorite thing in the kitchen

    This appliance is my favorite thing I own. I no longer use my oven because why would I? The air fryer hype is a thing because it is a thing. Everything is cooked to perfection. This is a great thing to have if you enjoy entertaining, came in handy for holidays when I needed more than an oven. I have been using it for almost a year. It has held up well, I do clean it often.

  2. A very versatile addition to my kitchen

    Arrived today Did not have to read the manual Everything was easy to understand & set The digital display & easy touch controls feel high end There is only one crumb tray.. I have ordered a second to place under the airfrying basket at the bottom of the second oven to catch juices as putting a roasting pan on the rack beneath it no doubt would affect how evenly food airfrys There is a 2 min preheat before airfrying begins & a cooling fan that runs when the airfrying stops The fan did not seem to run if i left the door open so if the fan running irks you & you dont have littles you can just leave the door open until it cools just know that the door does get hot
    I will try toasting a bagel next but plan to use bake function & set my preferred temp as opposed to using the preset ‘bagel’ setting since someone mentioned it torched their bagel Noticed the heating elements in the top portion do not seem well protected so aluminum foil will definitely be a must when baking things where cheese or grease may drip
    All in all i really enjoyed the first use of this appliance Its a bit hulky size wise but still space saves since it truly is a 2 in 1 Ill be interested to see what cant be cooked in this 12 in 1

  5. Burns toast edges. Noisy fan.

    I’ve already had unsatisfactory experiences with Breville (buttons stopped working) and Cuisinart (cord drew too many amps, said electrician; cord melted, outlet was affected, had to have it replaced) countertop ovens, so I tried this Ninja. It has its good points. Best one being you can still make toast when using the lower oven. Unfortunately it seems like no matter what kind of bread we are toasting the edges burn while the center is still bread. How does this happen??
    Two other points of dissatisfaction: 1) it’s quite noisy and 2) it gets noisier when the cooking is done and the fan comes on for several minutes. I’m thinking of returning it, but I haven’t because I don’t know what to replace it with. BUT can I live with it???

    I absolutely love this. We use it all the time. We recently upgraded to this from the last model. We love it even more. Very easy to use and is easy to keep clean.

    I am very disappointed in this product. I consider it very dangerous. I used it three times. I have taken it out of service and packed it back in its box. i don’t know how to get rid of it. It becomes extremely hot when in use. One is bound to suffer burns if it is regularly used. i have cooked with it three times, so it is used and I don’t think it is returnable. I am reluctant to give it away and expose others to its dangers. I also fear it may cause a kitchen fire if some flameable object is too close to it. I do not think it can be used safely on a non-stone or masonry surface. It works s very well. It it is fast. The cooked products are tasty. No complaints about how it works. It is just too dangerous to be used in my home.
