Review on 🦌 Bell Automotive Black Deer Warning Unit - PR by Christian Barnes

For starters I work 4 nights a week for 5-6 hours every night on the road. I live in a small town and spend a lot of time on the streets across the country. After encountering deer last year and seeing so many of them this year, in October I decided to buy them for our main machine. After installing them in less than 7 days, I physically watched 5 different deer look straight at me and then run in the opposite direction from my car! That's too much coincidence for me to believe they don't work. I will never own a car without buying them to install on them. And my kids will get them for their cars, too, when the time comes. First, it does NOT stop everything. You still need to exercise caution and protect yourself while driving. But these whistles provide some relief in the back of your mind. From what I could find online there isn't enough airflow below 30mph for them to work. They must be installed correctly. I wiped the spot where I put it with alcohol. They only stick once and won't come loose if you put them where you don't want them. Place them as close to the front of the car as possible (I have a newer Ford Fusion so I had to place mine in the front of the car). Be sure to place them according to the packaging on each side. Blow in and the closed one will whistle, but the open one won't. I can't hear them with the window open either. It was a great purchase and I am sure I will purchase many more over the years.
