I live in an area that is full of deer and not a single day would go by where I would almost hit a deer since I put these on my cars I have not had to worry about and accidents.

Mine also had one on each set without an open one. What's that about

I read some of the other reviews that tipped me off to the problem they were right. I am not sure if they work because I am not a deer we will see.

Poor performance. Intercepted deer this weekend. Totaled my car.

Be sure to check the product. One of mine was defective

I ordered 2 sets. One on each set is closed at the end, rendering them useless.
