Blinder works quite well, a friend of mine has it gives the policeman an error reading when they laser you. I've witnessed him being hit a couple times and the officer just gave a "?" look as we drove by. I know a pretty good group buy going on for the Blinder system on another forum if you are interested and/or if you want I could put my name in and just have you reimburce me if you'de like. 295$ shipped for the Blinder M-20 XTREME I believe. Banned in Cally, Minnesota, Nebraska, Oklahoma, Utah, Colorado, Virginia and Washington DC
PS I do not condone illegal speeding, speeding is bad
