Personally I have used
Valentine One units in all of my vehicles for many years. I know that some of the latest model radar / laser detectors have more bells & whistles (GPS and so forth) but for reliable advance warning covering all radar bands and laser, I highly recommend
Valentine One. Another advantage with Valentine is that if / when Valentine develops an upgraded unit, you can trade your older unit in for the upgraded model (kind of a lifetime guarantee that you can always run with the most advanced Valentine unit). Check them out at

Historically, travelers had to defend themselves against armed highway robbers. Today our police have become the armed highway robbers! It's got NOTHING to do with safety . . . it's all about collecting money and fleecing the motoring public. Protect yourself or pay up!
