The gadget is made by the circulations of hot air, rather than the old way of cooking using oil. It is easy to clean. You can simply wipe with a serviette. The maker doesn't require the addition of oil, so the popcorn it produces is virtually fat-free and an excellent source of fiber. The hot air circulation system eliminates the use of butter or oil reducing the calorie content. It is easy to use and can produce as much popcorn as need be.
