I have an Escort ZR3 laser jammer
They call it a shifter to be politically correct.
It comes with two sensors for both sides of the front license plate and on
built into a back plate mounting frame.
The unit does a self test when starting the car which tests all sensors and the alarm.
Also has a mute button to hit after you are legal.
I have been saved about 5 times with only front hits.
It's hard to stop smiling after this thing saves your ass.

 

Sorry but aren't laser jammers different than radar jammers? I suspect that laser ones are only for...LAZER jamming not K or X band normal radars. For those what do you suggest?

 

radar is FCC controlled, i.e., no LEGAL jamming transmitters...laser is FDA controlled (light) and legal from a federal perspective, some states make illegal..
