MATERIAL--ABS+PVC KEEPS FLIES AWAY FROM YOUR FOOD--Now you can enjoy a conversation over an outdoor meal without constantly swatting at flies. This lightweight, odor-free fan is designed to be placed on top of your outdoor or picnic table to prevent flies from landing on your food. HOW DOES IT WORK--The dots refract/bend light, which deters insects. This bending of light is not part of their nature. In the perception of these small insects, the bending colored lights seem unnatural and dangerous, causing them to choose alternative locations. WIDE USE--Whether sunbathing, playing cards, sitting by the pool, or dining on the back deck, you can do so without flies bothering you or hovering over your food. No more unpleasant mosquitoes crawling over your sweet treats; it works effectively in both shaded and sunny areas. CONVENIENT TO USE--Our repellent fan is cordless and operates on 2 AA batteries (not included). You can place it anywhere you wish.
