I have has my Laser Interceptor Quad unit for about 2 weeks now and was wondering if they work. I can tell you tonight on my way home on the highway they WORK and WORK VERY WELL. I am in the middle lane arount 11pm not many cars on the road and all of the sudden the system goes crazy, blinking light on the switch and rapid beeps and says the word LASER and some other words ( I could not make out ). It took me around 2 seconds to brake under speed and then I hit the kill switch on the jammers. Then about 100 yrs later I see the Trooper hidden on the side of the road with his nose sticking out and blacked out looking at his gun then re- aiming at my GT-R( priceless). I now have no doubt these Laser Interceptors work as advertised. BTW if you are out there Cliff should the system tell me what LIDAR gun is hitting me ? To be honest I was so shocked I might have missed that verbal warning of the type of gun, as the sudden beeps scared to sh*t out of me.
