I have been using this detector for 2 months now. The detector only goes off when I can already see LEO, I would say within 100-150 feet. Have tried different mounting location (near rear mirror and just above the dash at the middle) but nothing helps with the range. And the rear sensor is really terrible. 50ft after I passed a cop from behind, the alarm goes from full alert to nothing. :cry: I am always under the assumption that this detector should be able to detect radar from let's say a mile?
Not sure if I have a defective unit though...
