Keep flies and insects away from your meals with these innovative fly repellent table fans. Each fan features holographic blades with reflective patterns that spin at 5000 RPM, creating visual signals that flies find threatening. The continuous rotation and light reflections effectively deter flies from landing on your food, covering approximately 21.53 square feet per fan. The soft-stop blade design ensures safety by automatically stopping rotation when contact is made with an obstacle, then resuming once the obstacle is removed. These versatile fans offer dual power options for convenience. Use the included USB cable for continuous indoor operation, or insert two AA batteries (not included) for portable outdoor use. A built-in hook at the bottom allows you to hang the fan upside down, making it adaptable for various settings. The ultra-quiet motor operates without noticeable noise, ensuring your dining experience remains peaceful. Ideal for indoor restaurants, outdoor patio gatherings, camping trips, barbecues, picnics, and poolside relaxation. Each fan covers a table for one to two people, and the four-piece set provides ample coverage for larger tables and group celebrations.
