90's, tried the V1 around 2003 but found it had too many falses so I sent it back within the 30-day return period. Bought Escort 8500 instead and later another 8500 for my wife's car. Now both are developing problems. Both seem to be less effective, one often goes into self-calibrate mode, the mute button quit working on the other one. I am looking at getting a new model. I can get $80 credit for one of the 8500 (unfortunately not both) with Escort towards a new model but am considering giving the V1 another try. Looking forward to reading user reviews and thoughts.
