Highlights

Integrated Pro Cook System Achieve the perfect level of doneness from rare to well-done at the touch of a button using the integrated thermometer and Auto Temp Detect Intelligence, eliminating the need for guesswork.
Smart Surround Convection Features a high-velocity fan and rear heat source that provides up to 10x the convection power of a traditional built-in oven, delivering an all-around crisp without the need to flip or rotate food.
10-in-1 Versatile Functionality A multi-purpose kitchen powerhouse with 10 specialized cooking programs: Air Fry, Whole Roast, Air Roast, Bake, Dehydrate, Pizza, Broil, Toast, Bagel, and Reheat.
XL Family-Sized Capacity The extra-large interior accommodates two 9×9 baking trays, a 12 lb. turkey, or up to 9 slices of toast simultaneously, making it ideal for large family meals and entertaining.
Rapid Preheat and Cooking Saves time in the kitchen with a lightning-fast 90-second oven preheat and cooking speeds up to 30% faster than a standard full-size convection oven.

Pros & Cons

Pros

  • Exceptional Versatility and Performance: The 10-in-1 functionality allows users to air fry, bake, roast, and dehydrate with consistent results, often making traditional ovens obsolete. It features a large interior capacity that can accommodate whole chickens, 13-inch pizzas, or multiple trays of food simultaneously.
  • Rapid Preheat and Cooking Speed: The unit features an incredibly fast preheat time of approximately 90 seconds, which is significantly faster than standard full-sized ovens. This efficiency allows users to start cooking almost immediately and reduces overall meal preparation time.
  • Integrated Smart Thermometer: The Pro Cook System includes a built-in thermometer probe that monitors internal food temperature and automatically shuts off the unit when the target doneness is reached. This feature eliminates guesswork and ensures meats are cooked perfectly and remain juicy.

Cons

  • High Noise and Vibration Levels: A frequent complaint is the excessive noise generated by the convection fan, which some users compare to a jet engine or an airplane. Additionally, several reviewers reported distracting metallic rattling or vibrations during operation.
  • Large Countertop Footprint: The unit is quite bulky and deep, requiring substantial counter space and clearance from walls due to its rear-venting design. Its size may be problematic for smaller kitchens or standard-depth countertops.
  • Challenging to Clean: Maintaining the interior is difficult because grease and food splatters can easily reach the exposed heating elements and the back fan. Users noted that baked-on residue is hard to remove and the crumb tray can be tricky to empty without spilling.

    We didnt like how the air fryer work. A cheap air fryer would fully fry making crispy and extra well done. This product would just heat ex. Sweet potatoes making soft but not crispy and fry the potatoes

    Works as intended. Going from a cheap little airfryer to this was definitely worth it. The multiple racks is a plus.
