I bought my v1 about a month ago and 2 days later i was coming back from yuma to phoenix. right in the buckeye area, i made a stop and leo was pulling out of the gas station with ka on. i was following a group of speeders(rabbits) and i was the last car. before v1, i would follow a group of speeders all the time. if it wasnt for my v1 i would of kept hauling ass with the group and surely been pulled over. leo was right on my ass for a couple of miles with ka on and my v1 just screaming the whole way. since ive had it, its saved my ass about 6 times. its paid for itself im sure already. my 2 cents. its an awesome detector.
