I have a Valentine One radar and it's great, but unfortunately it doesn't intercept a police car only the radars and lasers of the police.
This morning, I went to carry my gilrfriend to the airport, but on my way of the return, a blue Chevy Impala undercover cop came to intercept me. I never saw this car from behind me and I said to myself WTF my V1 didn't show any threats at all. After, I hide my radar very quickly and when the cops said to me that I running 140Km/h in a 100Km/h zone, My first question to the police was to ask by which system he caught me ? He said only by visual speed evaluation. :roll: Thus, this subjective evaluation is very contestable in court.
But overall, since 4 years that I have the V1 I never had a speed ticket and it saved my ass hundred times here in Canada and in the States. :good:
