I've had several different brands over the years. Beltronics, Escort, Cobra and Whistler. Never had a Valentine. They all detected radar OK. Major difference I found was some would give a lot of false readings, particularly for LIDAR more than others. Beltronics and Escort are the same company and I definitely did not find either to be vastly superior to any other out on the road. I also found all them to pick up instant on at the same time the LEO nailed you. Right now, my Cobra sits on the bench because I ride too much in western VA and they run radar detector detectors. There are several Cobra's under $100 that are IMO as good as the rest.
