Hey all, I have an Escort 8500 Passport X50, and it works great and has saved me numerous times. I've never had a ticket while using it and it has saved me from laser guns as well. Granted there were other cars very close to me at times when my escort alerted me of a laser gun. None the less, the thing does its job. Its a few years old now so i was just wondering if it weakens? or if the range of the radar detector gets worse over time? My initial thought is no. but I was just wondering. Maybe its time to get a 9500ci?
