The radar detector is made by “Rocky Mountain” and I am a proud user of it. The company claims that it can scramble the police radar, but I can’t prove that. All I know is that it does detect the police radar so far in advance that I don’t see how they can get me. I bought the device because I drive a “Carrera S” and feel that I have the right to drive fast given certain safe situations like driving on open highways in the desert. What is the point in spending all that money on a car if you can’t enjoy it? Believe me, I normally drive the speed limit or just slightly above as do most people. It’s all about money not safety when it comes to issuing tickets.
