I think these actually work. Proof? I think it's worth the $ because since I put them on no squirrels have run in front of my Volvo XC90. Yes it was a problem. I've used these whistles in the last 5 months and so far I haven't hit a deer, or other animal....so I will keep using them. These have nice stickers and seem to attach well. I like them.

We use them to keep away the deer as we don't want to hurt them or have them destroy our car. They make a sound that you can't hear but the deer can and don't like so they run away from you!

These things are great!!! I hit a deer before buying them and since I've had them on my vehicle I have no problems at all. Deer, raccoons, cats, squirrel basically any animal found in Michigan runs away from me.. Have recommended to at least 10 people so far.

Purchased the deer whistles after being in a deer accident. I love the size and mounted them in the grill of my SUV. They blend so nicely you don't even notice them.

I love these they really do work was driving down a dirt road and there was some deer standing in a field near by and they went the other way because of the whistlers these do work.

I know they are working because animals freak out and run away now when I'm driving toward them. Before the animals would usually just stay right in the road or close to it. I have a brand new car and hadn't gotten around to putting these on for the first few months. That's how I can compare the difference.

These deer whistles work wonders I hit a deer a few weeks ago and I ordered these deer whistles to help. Since installing the deer traffic has been down on my road and I have not even come close to hitting any since.

Saw a deer the other day, she just stood still and looked, didn’t run out in front of us. We try to keep these whistles on all our vehicles!

I was skeptical about these at first, but I bought them and put them on all three of our family's cars after my husband hit a deer last autumn and I missed hitting one by a hair this year. Two times since putting them on my car about a month ago, I have seen deer stop and back off from the side of the road. I'm not sure if it was coincidence, but I believe these made a difference. Enough so, that I bought a set for my co-worker who hit a deer a few months ago, too. Inexpensive enough that they are definitely worth a try.

I bought this for my brother because he hit two deer in one month. He has been using it for about a year and hasn't hit another one. He has seen a few on the side of the road, and some running away. Could be they normal course of events, or the result of the Warning System. All that matter is that he hasn't hit another deer!! Totally worth it to us.

The other day, I was taking my family to the airport at 3:30am, and while driving down I-5 at 70 MPH in pitch black, a deer appeared on the right shoulder, about to walk right in my path (I was driving in the right lane). Just as I began to slam on my breaks, the deer suddenly turned around and leapt off the road out of my way. Unbelievable! I've NEVER had a deer do that before, and I've encountered plenty (although not on I-5).

My wife was laughing at me when I put these on, but quickly changed her mind after this happened.
