Works great as advertised. Is much more sensitive than the old Cobra it is replacing. The only problem I have had with it is it seems to lose its compass calibration once every couple of days. Not really a big deal, but it was one of the main reasons I paid extra for this unit, the compass. It always calibrates right back up with no problem, it just doesn't hold it very long. Sometimes it will de-calibrate its self, pointing in the wrong direction. Other times it will just freeze at one cardinal point, like SE or something like that.
