With my use of the deer whistlers they work.
Now one has to understand how they work.
Lets say you see a deer in the ditch and the car has no deer whistlers installed. As the car approaches the deer the deer will more than likely panic and bolt into the one coming path of the car Ouch.
With the deer whistlers clean and properly installed they will start to high pitched squeal at 40 mph and up.
The high pitched squeal projects the sound much louder than what the sound of the car is making so the deer get a heads up of the approaching car. 90% of the time the deer are not startled or panicked and remain as they were.
