I am very happy with my oven. I love the wide variety of cooking modes. The air fryer option is a great addition to the traditional oven although I have found it is important to place the food in the lower half of the oven to keep from burning the top. I did need to use an oven thermometer to calibrate the cooking temperature but it was really easy to make the adjustments and now it cooks beautifully. 
I am still learning the wi-fi capabilities. The ability to start the preheat remotely and the phone notification when it reaches cooking temp are surprisingly useful and I really appreciate being able to check remotely to make sure the oven was turned off. I just figured out how to use the Drop App to allow the recipe to control the oven from the recipe. Interesting but I don’t know that it will be particularly useful. If there is a way to add recipes to the oven menu I haven’t found it - and I think that would be more useful than the app.
All in all I am very happy with my purchase.
