This clone LED jammer did surprisingly well against the Pro Laser 3 - especially considering the size of the target vehicle, large headlights and spotlights. The test vehicle has a 'walkie talkie' inside, transmitting so you can hear the jammer alerting.
Whether you want / need rear protection is something you need to look at (based on your area, and the tactics used by police), but yes you can have them on both front and back, yes they alert you inside the car (that you are being scanned) and yes you can shut the jammer off.

Do I need one for the front and the back of the car? Does it give me a warning in the car that I'm being scanned? Can I easily turn it off so the cops don't get suspicious?
