I am in love with this toaster oven! We absolutely love the air fry feature as i used it for frozen french fries and frozen zucchini. It definitely heats up fast as i tried to make a small frozen pizza which turned out excellent. Also, while the air fry feature was in use i decided to re heat a fast food cheeseburger and i like how i removed tbe top bun and placed on the air fry rack. It toasted the bottom perfectly leaving the top soft. By far one of the best products out there.
