Blinder laser jammer and Escort X50 radar detector are a great combination. They have paid for themselve 10 fold and work GREAT!

The Blinder I have on my car was expensive, but comes with both front and rear jammers. I have jammed an officer using laser while I was going 100mph. I think I paid around $700+ for it plus the installation. The Escort was under $400.

A little advice though. Follow the instructions precisely when using the laser jammer. You are suppose to slow down to the speed limit, turn it off completely, and let them get a proper reading otherwise they will think something is up.
