The blades are designed with a holographic dot pattern that bends and refracts light as they rotate, creating an unnatural environment that confuses and scares flies and effectively keeps your food and drinks clean within the fly fan repellent coverage area. The flying fan of the table is made of high-quality blades that are soft to the touch, flexible but not fragile. For safety, the blade stops immediately when it touches an object and resumes work after the object is removed. You are free to enjoy peaceful times without worrying about injured hands or children.The effective fly fans for tables are powered by 2 AA batteries,not included batteries.
