This Hayes K5 air oven is designed with double glass for better heat insulation. The inner container is enameled and oil-proof. When it is dirty, it will be cleaned with a light brush, which is more convenient. There are four heating pipes and fans at the top, which can quickly force out food grease and heat it more evenly. There are quite a number of accessories, including slag receiving tray, baking tray, fried net, rotating cage (for popcorn) and rotating fork (for roast chicken). 10 inch Qifeng mold; 16 chicken wings; 9 egg tart; 30 biscuits; 12 breakfast bag, much larger than the capacity of air fryer. The operation panel is designed at the top with moderate height. You don't need to bend over to see, and the upper and lower pipes are controlled independently. Remember to bake it empty when you use it for the first time. After I bought it, I tried dried fruit with the function of dried fruit and beef jerky with the function of air frying. The taste is not much different from that sold outside. This is a surprise.
