Love the size of the Deer Screamer. This whistle received high marks from customers.I also purchased the "Save-A-Deer" whistle. I now have the Deer Screamer on the right side of the bumper and the Save-A-Deer on the left size. Hope they work in Deer country.

Small and easy to attach to vehicle. Here's hoping it works when deer coming flying out of nowhere!

It's been about 2 weeks since I put the deer screamer on my suv, and I've not made contact with a deer! I still see them, but it does seem like they hear the whistle, stop and look.

This does work as described. ALL animals turn, stop at least and the deer go back into the woods. I think it does a good job at least where I live. It was worth the extra money to get this one over the pair I used to purchase. I can see the animals react. Recommend.

I installed Deer Screamer as instructions advised, First night on my way to work a coyote ran right in front of me, I also passed 2 groups of deer on the side of the roadway and I did not see any reaction from any of them.I can tell you the Deer Whistle did not seem to bother the Deer at all but boy did it bother me, it is very loud inside my car even with windows up and radio on.Had to keep radio at a very high level to drown out the Deer Screamer.By the time I arrived at work the Deer screamer was silent, I looked at where it was installed to find that it was no longer on my car. The tape that came with it was still present but the Deer Screamer was gone. Just a felt like piece still taped to my car. Now I have to find a way to remove the tape.Not sure if I should be upset that its gone or happy that I don't have to hear that sound again.

Not sure if it works yet on deer but I did notice some turkey vultures cleared off the road well ahead of me like they didn't know what was coming at them. Most difficult part of this item is finding a suitable flat space that it will stick to on the front of the bike. I didn't want to use epoxy which would be permanent so I had to find a smooth place that the supplied 2 face tape would adhere to.........wound up sticking it on the mirror base where it meets the fairing. As a result, it is positioned so that it is pointed a little bit downwards rather than directly head-on but I figured it would still work as designed by catching all the air hitting the fairing as it sweeps around the mirror.

Greatest deer whistle ever. Put it on my truck and ever saw a deer again. Honest!!

I feel they're a little expensive..
