Seven Sparta 4 Pcs Deer Whistles Deer Warning Devices with Waterproof Adhesive Tapes for Car/Truck/Vehicle/Motorcycle(4)

These deer whistles really seem to work! I've been using them on my car for a few months now and haven't had any close calls with deer. They're easy to install with the included adhesive tape and are super affordable. I feel much safer driving at night, knowing these whistles are deterring deer from the road.

While I can’t speak to the exact science behind the SEVEN SPARTA Save a Deer Whistles, I can certainly vouch for their effectiveness! Living in the Pinelands, where deer are as common as pine trees, I’ve been driving for 8 years without a single close encounter with Bambi and friends. 🦌These little gadgets are super easy to install and seem to do a fantastic job. My nightly drives through deer territory have been uneventful in the best way possible. Whether it’s sheer luck or the magic of these whistles, I’m just grateful that I’ve managed to avoid any deer collisions.They’re compact and unobtrusive, so you can stick them on your car without messing up its look. Plus, peace of mind is priceless, especially when driving through areas with high deer activity.If you’re like me and want an extra layer of safety for those twilight and nighttime drives, these whistles are a great investment. Who knows, maybe it’s a bit of deer whispering magic at work. Highly recommend!

These work great, BUT the minimum speed is a bit high.Took a three week road trip around the midwest, including back country AR, MO, TN and KY.Saw a lot of deer and more than once saw them startle and bolt a good distance ahead of my truck.BUT 35 mph is TOO HIGH a minimum speed.We almost hit a doe and juvenile that came out of brush along the road RIGHT in front of us at dusk on a back road around 30 mph.Would give this FIVE STARS if the minimum speed were lower, like 20 or 25 mph, so they were more effective on the back roads, where you're also more likely to encounter deer.

The area I live in has an over abundance of deer. The deer seem to enjoy playing on or around the road. Some people go as far as saying deer are suicidal. It seems that way at least. Even though we live off of a main highway, it's still a good 8 to 10 miles to civilization. The speed limit is 55 but with the deer population, it's good to go slower, especially when it's dark, foggy, or raining. I got these whistles to add an extra layer of protection when driving because I drive in the dark a lot. I usually see at least one deer on the road every morning driving to work. I just put these on my car four days ago. I don't know if these work but I do know that I have not seen one deer since I put them on. On my drive I have observed dogs, cats, cows, goats, sheep, rabbits, and horses to see if they have any reaction to the whistles. These are all the animals that I pass every day and none of them have reacted any different than they normally do. Installation of these whistles was very easy. Basically just peel and stick. Make sure to clean the area with alcohol before sticking the adhesive to your car. I have almost a 50 mile drive to work and these seem to stick well. I check them when I get to work to make sure they're still on the car and I check again when I get home. So far, they have done fine and feel sturdy. Also, when you stick these on your car, be sure to use two different whistles. One has an open end and one has a closed end. The instruction sheet in the box will tell you which one to put on the drivers side and which one to put on the passenger side of the car. I did just what the instructions said and as I said before, I have not seen one deer since putting these on. This is a low cost way to give me some added safety and peace of mind. This, by no means, takes the place of being cautious. You never know what a wild animal, or any other animal, may do. I will continue to check these and watch out for deer on the roads and I'll try and remember to report back in down the line.

I always have these on my pick up! This item comes with 4! So important for the safety if these innocent animals!

Can't tell you how many times that deer have been along the road and have run off when they hear these whistles! Have definitely saved my van several times! Have had these for 2 years and great quality!

The quality of the adhesive definitely needs improvement for colder environment.

I read man reviews on deer whistles when I was curious about them. Many reviews said they didn't work. I don't know if they installed them wrong or were born pessimists. It would be hard to actually do a study... if you installed them and never hit a deer, could that be pure coincidence? However, when I moved to NH where there is a big deer population, I decided that they were worth a try. Well, I didn't just never have a deer jump out in front of me but many times at night observed eyes illuminated by the headlights at the side of the road ready to cross and then suddenly turn their attention on my car and back off the road. Several times I saw deer eyes each side of the road all focused on the car not moving. One time it was a racoon at the side of the road starting to cross, then turned its attention on my car then backed off the road while herding several small sets of eyes (her pups) off the road. They work and will save lives and your wallet of repair costs.
