How does it work:The dots refract/bend light which scares the flies. Bending light is not a part of their DNA. In their little fly minds, the bending colored lights are not normal in nature and it appears dangerous to them.   They will always choose to go somewhere else.

Chemical-Free Tabletop Fly Fan: The fly repellent fan uses a physical and chemical-free method to protect your food and drinks from flies.   No side effects on anyone.

Reflective Fan Blades: The blades are designed with the holographic dots pattern that bends and refracts the light while spinning, creating an unnatural environment that confuses and scares the flies to stay and effectively keep your food and beverages clean in the fly fan repeller coverage area.

Soft Blades & Stop-On-Contact: The fly fans for tables are made of soft-touch and high-quality blades that are flexible but not fragile.   For safety sake, the blades will immediately stop when they contact an object and resume working once the object is removed.   You can freely enjoy your peacetime without worrying about hurting hands or children.
