🦌 4 Count Auto Deer Whistle - Ultrasonic Wildlife Warning Device to Save A Deer - Easy Mount Adhesive for Auto, Motorcycle, Truck, SUV, ATV - Black Review

I don't see their value because I don't know how well they work. I drive at night and meet a lot of deer. I bought them after I found one. It was fairly easy to install and stuck well. After installing the deer whistle, I encountered another deer on the road and it didn't seem to notice or respond to the whistle. It worked when I blew the horn so I'm not sure if the whistles work or not.

Cats first seen running off the road as a car approached, ears pricked and looking my way. Doe stopped at the side of the road, ears pricked, looked straight at the car, turned and ran away. So far there have been no encounters with dogs or coyotes. This appears to have prevented at least one deer-car collision.

Lasted a few months and then fell off. I can't understand why companies that sell these types of adhesive products don't invest in better adhesive applications that are actually worthwhile. Although for the price it's not bad. I use in Wisconsin during deer season or when traveling to remote areas with lots of deer/traffic accidents. I'd rather pay more for a front duo that I could permanently attach to my jeep and never have to worry about the adhesive failing and falling off...
