Have tested it on long trip. It found police who were trying to hide in a classic speed trap. It sometimes goes off in town detecting X band interference I guess. Noise can be a little annoying, but it is loud enough to get your attention in a speed zone. Still can't pick up police who tail you at night. Nothing can.
