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 oven as long as it doesn't rattle

    Overall the functionality is great. I really like that I can cook items in the bottom part and not have my toast taste like last nights dinner. Never had an air fryer before and this seems like a nice feature. Only complaint is that the cooling fan (there are two fans, one for the convection/air fryer and another to cool the internal electronics behind the buttons) rattled so badly that it sounded like an air compressor. I was going to return the unit but decided to take it apart and glue what appears to be a small ‘PC’ style fan into the housing. This solved the noise and was easier (for me) than driving back to the store. Most people wouldn’t have the tools but I fix and maintain equipment for a living…

    I really appreciate the dual cooking! Especially while I’m in between ovens LOL. And this really is a lifesaver. This is something that I would definitely gift someone for a housewarming gift or someone who moves into an apartment. This is perfect. And this is perfect for someone who cooks a lot like me and especially during the holidays you can have a whole Force going and completing some meals.

    Cooks way too hot and burns everything on the right side. You constantly have to rotate things since all the heat shoots out of the right side. Burned half my pizza while the other half was still raw

    I got on sale for $220. I love the toasting for bread. I love the fact that you can cook two meals and finish them at the same time. It’s just overall a great piece for the price. The only thing I don’t like is it makes sounds when it’s done cooking, but it’s a fan that cooling machine down.

  10. Good Experience
