This is the best laser jammer on the market. Yes it really works and is way better then a blinder unit. It calls out the type of laser that is hitting you.
Laser Interceptor, 2 head unit. It works on any car.
Used for one month (then I sold my car and now just dont want to install it on my new car)
Retails for $700
Not legal in all states, check that your state is legal first.
Here is a video of the Laser Interceptor vs True Speed laser (one of the newest, hardest to defeat lasers) http://www.youtube.com/watch?v=hrecgnTQrLQ
