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. Beautiful design and great performance so far!

    I recently purchased this Air Fryer and so far I’m really impressed. Physically, it looks beautiful — the stainless steel color is very sleek, the buttons feel high-quality, and the LED display is clean and easy to read. I also love the dual doors; they look modern and make the oven feel very premium.
    For my first test, I followed the instructions in the manual and then tried toasting some bread. In just about 3 and a half minutes, the toast came out perfectly — nicely browned and crispy on the outside while still soft on the inside. Of course, the result depends on the type of bread and personal preference, but I really liked how evenly it toasted.
    I plan to test it more during Christmas when I bake my cookies and will update my review then. But for now, the oven looks gorgeous and is performing really well.

  3. Owned for almost 3 years

    We use the oven EVERY DAY. We start our day with toast and it’s the fastest toaster I’ve ever owned and I previously had a Breville and toast took forever.
    I love being able to cook baked chicken in the bottom, air fryer red potatoes above the chicken and then roasted veggies in the very top section. The entire dinner at once! I have made many brownies, cakes and muffins in the lower oven and today my daughter baked an apple pie and it came out perfectly.
    I use the thermometer quite a lot to make sure everything is cooked through and it’s always measured spot on when I compare it to my instant thermometer.
    Another thing I love and nobody talks about…there are no elements or burners in the bottom section. So today when my daughter’s apple pie overflowed (and she forgot to put a tray under it), the sticky caramel sauce went onto the bottom of the oven and there are no burners there for it to start smoking or anything.
    On that note, I use non-stick liners in the bottom which easily wipe clean. Here’s a link to the liners I usem, they just need to measure 12×12 https://www.amazon.com/dp/B0D91H64R4?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_2&th=1

    I live in AZ and I almost never have to turn on my big wall oven in the summer months and heat up my whole house.
    On a similar note, I especially appreciate how quickly it preheats…no more waiting 15-20 minutes for my big oven and it cools down quicker too.

    I obviously love this thing and hope they never stop making it.
    I love the look of the newer version with all stainless steel compared the one I have from years ago. I would like to buy it but my original one is still working super well and it’s hard to justify spending more money for it to look good.

    I bought mostly to assist for holiday dinner. I made my stuffing in it and worked beautifully! I tested it before the holiday and made homemade mac n cheese and baked perfectly! Love it!

    I use this bad boy almost every single day. I use it more than the oven in most cases. So far it has handled everything that I put in it!

    I was so excited to purchase this toaster oven. After receiving it, that excitement went away very quickly. The top portion could be a little taller. The toaster part on the low setting doesn’t test at all on the next higher setting Burns everything. I am disappointed to report that I do not recommend this item

  8. This thing does it all

    This little machine can do just about everything. We’ve used it almost every day since we bought it. We could pizzas, chicken strips, egg bites, even bacon in this thing. It can bake, toast, air fry, etc. It’s so easy to use, we have not used the oven much since getting this ninja air fryer/toaster oven. It is the size of a large microwave. Very happy with this purchase.

    We loved the single oven. This one is a little confusing and the controls are hard to read. My wife doesn’t want to use it at all.
