well the problem with that above is that it is essentially just a laser scrambler. I haven't had my 8500 for too long, but everytime I've passed a cop, they were using radar. Not once has the laser warning gone off. Yes, it's true that laser is too quick for most radar/laser detectors, so you really just have to hope they aren't using laser. Now the biggest problem with that scrambler is that laser is 100% line-of-sight. The only way that scrambler could work is if the cop aimed it at your license plate. Sometimes cops do, sometimes they don't. Can you take that chance after spending $299??? Like I said before, it's all a matter of opinion about these things, but I say use the more conventional detectors and stay away from "scramblers".
