Had the thing for almost a month, got a few saves but nothing my RX65 wouldn't have saved me on.
Today I got a save from 0.5 miles out, LEO hiding off to the side at a traffic light - was around a bend so pretty good off axis. Then I made a left turn and the rear horn continued picking him up for another 1.5 miles. Behind a hill. In heavy traffic. I only wish I'd had time to loop around and see how far the front horn would've sniffed him from.
I love my V1
