Review title: Gives false alarms and not very reliable
Product review: Bought it around thanksgiving as it was one of the sale items. Just to test it, drove around for over a month, both within the city & on interstate. It constantly gave false readings when, during daytime, there was clearly no visible sign of any police car in front or behind me, driving on highway. I tried all the various frequency settings as well, to eliminate these but in the end I just gave up. At night, the sharp blue led will draw attention to you when it lights up.
