So, your cheap radar detector died so now you don't trust expensive ones? Is that how it works?
I've got a V1 that is 4 years old in my DD, escort sr7/zr4 in my wife's car (3 years). Both the V1 and the Escort have been great...no problems and saved multiple tickets.
I've got a brand new 9500ci that will be going in my Z soon.
