I'm having fun testing, but I learned too late that the fcc radar detector test date means more than just about any features your looking at. I've seen top detectors on Amazon marked way down, and their test date was 2011? Outdated technology, far lower sensitivity (chip and horn in detectors far exceed that old stuff from yesterday). If you see anything on Amazon, Ebay, bla,bla, check its fcc test date to assure your getting the top tech in detection you deserve,
