All I can say is that when its up and running, Ive never got a ticket in 5 years.
If there is a cop somewhere ahead, this thing tells me. I love mine. You have to spend some time with it and learn how to 'read' it (distinguish how it sounds off a false target vs. a real one, and also instant-on-radar warnings ahead of you). It will warn you if there is a cop coming from behind (which I find worth the cost of the thing right there) Its also cool how the directional arrows light up as you pass a cop on radar, FRONT...SIDE...BACK...Missed Me Bitch!!
