I had a jammer for a few months now and never been hit with laser. I almost thought that my blinder wasn't working.
Today coming from work, going up hill on I-90 MASS, I noticed a car turning the lights OFF in the median Far on the other top of the hill. I knew that it was a LEO. After a few second my Blinder went off, My RX65 went off for a few times as well. I did not get the disctance but I know it was more than 1500ft. Blinder was on until I was on top of him. Was more than 15 seconds. Speed limit 65 and kept my speed below 75.
That was a great experience, great to know it works. My car had plenty of salt because it was snowing a few days before. Blinder was clean. I guess the salt helped as well.
