MOARMOR Deer Whistles for Car/Truck/Vehicle/Motorcycle Car Deer Warning Whistles Deer Horn for Car(4 Pack with 8 Adhesive Tapes)

Obviously there’s no way to know for sure if they work, but I swear the deer do run away instead of into the road when I’m coming towards them. Just be aware it does say you have to be going at least 35mph for them to work.

I have come upon deer on the side of the road atleast three times since putting these on my car and every time the deer stopped or did not continue to move into the road. Win win.

They are so loud I can hear them.

Living in the backwoods of Kentucky, deer are always a problem and the fear of hitting one is very real. I have purchased these several times and installed them on all three of the vehicles at my house. Since installing, we haven’t even seen deer standing or crossing the road. 10/10 would recommend, especially when it comes to safety.

great for what i need it for

Item worked perfectly. Hopefully, they will keep the deer 🦌 away from my wife's current car. She has already had a deer 🦌 strike with her previous car, before I installed similar deer 🦌 whistles. Fine after that. Before I got these, right after she got her current car, she had to dodge a deer 🦌 on the local interstate!

I haven't hit a deer, so I'd say they work great and I live in the country.

One has already fallen off!
