Customers are saying

Customers have good things to say about the air fryer, ease of use, and smart finish features. Many appreciate the oven's ability to toast and its overall versatility. However, some customers mention the oven's size as being too small for larger items, and others note inconsistencies in temperature and cooking times. The price point was also a concern for some buyers.

    this oven is great, my old one broke on me and I wanted to repurchase the same one but it was out of stock and I bought this one out of need and I have zero regrets. the dual oven feature is great it saves me so much time when cooking it works better than my actual stove oven. its amazing!

    Baking and convection bake are quite good. Air fry is OK but basket is hard to clean. Smart finish is a clever addition.

    Replaces toaster oven and stand alone air fryer. So far handles toaster functions with ease. Air-fry takes some time to learn best settings which are a bit complex.

    This toaster, air fryer, and baking oven is absolutely wonderful. The heat produced compared to the full size oven is so much nicer...the house stays cooler...and the food cooks much faster.

    Great replacement for a toaster oven. We are using this more than our gas oven now - more efficient, less toxic, better cooking experience!

    I bought this for my spouse since our other toaster oven was very old and not toasting well. I bought this one because it had so many other features we can use. With just the two of us, I think we will be able to use this double oven more and our big oven less.

    This dual air fryer/oven it’s amazing. I love having the ability to tackle multiple things at once in a relatively small foot print. Even has a thermostat to plug into your poultry or steak to make sure you get that perfect temp. It’s a must have if you like to cook multiple things and save time and space
