For what it is worth, I am including two links here to an earlier thread in this forum on the subject of the pros and cons of various concealed radar/laser detectors/shifters for our vehicles, that I think many of you will find interesting..... I am currently using the Escort Passport 9500 ci system and have had almost two years of happy motoring where I am convinced it has saved me many times and has paid for its original expensive cost and custom installation.
