Living out in the country, I am constantly watching for deer. I knew these worked because I had them on my car. When my car ended up wrecked, because someone backed into me, I knew my next vehicle had to have these.
I ordered this new set and it's been perfect. They definitely work and they save lives of deer along the road but also save your vehicle from the massive amount of damage done when you hit a deer!
I have had two family members hit a deer and one went through the windshield and the other destroyed the front end of the car.
No one wants to hit a deer. Having these Seven Sparta 4 piece deer whistles applied to your vehicle will save you damage to your vehicle and save the life of a deer which would otherwise be more likely to run in front of you if you didn't have this device.
I have used on a car and an SUV. They will also work on any truck, rv, motorcycle or any other recreational vehicle.
