Like all radar detectors you have to read the fine print. Go to Whistler's website at whistlergroup(dot)com and check the specs on this radar detector.All the xtr-140 does is detect VG-2(a very outdated band that very few police officers use) and Safety Warning System - SWS(Aka emergency vehicles - a band that theoretically does not exist). So in other words you are paying for a rock. I do not even have to buy it to know how lousy this Radar Detector is because I am educated.Before you go out and buy a Radar Detector educate yourself. Don't buy it because it looks good or it flashes lights at you. The main reason you buy a Radar Detector is to have it detect radar guns. Educate yourself. Search for Radar Roy on the web and take advantage of his years of experience and testing with Radar Detectors. Then see if you are still interested in this Radar Detector. Trust me you won't be. Be smart America.
