I used to think that Radar Detectors were a total waist of money. While your still banking that the police officer is driving down the road with either the radar on or clocking every single vehicle he comes in contact with. I've had mine go off and passed it off as a false alert, and only to have one of my city's finest drive by at the red light. I just traded my diesel truck in for a 400hp car, and let me tell you... The $300 bux i spent on this is CHEAP insurance as it has already paid for itself!
What's great about it: SUPER sensitive
What's not so great: Don't know were signal coming from
