Review on 🦌 Enhance Road Safety with Seven Sparta 4PCS Save a Deer Whistles: Deer Warning Devices for Cars & Motorcycles by James Brault

They work the same as what you can buy at Walmart. I know they work because the animals go mad and run away when I walk up to them. In the past, the animals usually just stayed right on or next to the road. I have a brand new car and didn't have time to put it on for the first few months. This is how I compare the difference.
