I've been reading a lot of posts from some of the participants of the latest Gumball 3000 and this year’s co-winner, Torquenstein, used a combination of the Valentine 1 and the Blinder M40 laser jammer. If the police in your area use laser speed detection, you may want to research laser jammers. I've been reading some remarkable things about their performance. Of course, here in Virginia, radar detectors of any kind are illegal, but last I heard they don't confiscate them anymore.
