8Pcs Deer Whistles for Vehicles Wind Activated Black

I have ordered these before, for me they work well. Have made deer turn away.

Easy to install, lets hope it helps. I have used products like these through the years, like since the mid 90s! and it us just a must have for me. There is really no way to tell for sure if they work, but I still use them. They are inexpensive enough that I find them worth while addition to my car. I still keep a close look out for deer, especially right now while they are active (extra precaution at day break and sunset). I live in a rural area, and while it isnt going to necessarily stop a deer already in motion, hopefully it stops one from decided to pick up movement as it hangs out near the road.I needed a set because I just got a new (to me) Jeep.Shows only one whistle being needed (applied on passenger side of car), but I used two. I figure, why not?

As the title says I’m not really sure if it will work but the parts work. I bought this after a deer jumped in front of my car going 55+MPH and I almost died due to my hood coming loose which went over my windshield and it was either oncoming traffic or a 3rd ditch. I chose the ditch. If I brought it to a mechanic the parts and labor would’ve easily been $2500-3500+ but fortunately I had a mechanic friend with the same car and a room mate whose also a mechanic and I ended up only paying $600. With that being said the life of myself and those around me are well worth $10 (even if it is just a placebo). Out of the pack of whistles I bought one worked while the other didn’t (intended that way). My only complaint is the sticky tape doesn’t peel well and the styrofoam began to peal off. I fixed this with gorilla glue-clear grip -concrete adhesive (there’s better products on the market but it’s what I had today). So far - two rides and no close calls with deer. I’ll let you know if any of that changes but for now it works

I like these. Nice & small without being noticeable. I cleaned the contact surface with some rubbing alcohol & they stuck really well.

These work! I've seen deer near the side of the road Rush into the woods or away from the highway as I approach.

While I have not installed these yet and therefore cannot comment on their effectiveness, absolutely no instructions were included. This is a gift and instructions should always be included.

The CITKOU 8Pc Deer Whistles are a must in rural Georgia - the deer are always on the road right-of-ways! The CITKOU Whistles are excellent quality, easy to install with an amazing adhesive pad attached to the base, the whistles are also removable from their mounting bases for thorough cleaning of the devices and the mounting area on the vehicles. It could be nothing but coincidence that since starting to use these devices some 20 years ago our family has not experienced ANY deer incidents with our vehicles - we definitely see them scampering away on the road shoulders & thankfully so!!

They both definitely whistle. One you can hear. The other you can't, but your dog can.
