CANORME Portable Table Fly Fan for Indoor & Outdoor Dining - Keep Food Clean & Bug-Free | Perfect for Picnics, BBQs, and Patio Meals

These are great. I wish every restaurant patio table had these.If you put the fan right next to the food or drink - it works - but if inches away, of no use!We use these on our outside table for dinner almost every night. They last a long time. They are very safe and they work.
