Ah man, not this idiot again. Yeah that's laser jammer Dave, the guy who proves his jammers work by having them trigger a Cobra RD and never actually testing it against a lidar gun. The guy is a moron and a scammer selling bogus "jammers" that don't do a thing and he has long since been banned off the forum. A few people have bought his products. I've had a chance to test one and it didn't even power up, much less jam. Either way, he keeps popping up under new names, but it's the same thing all over again.
