I was testing my V1 out in my friends car while parked in someones driveway. I got an X alert (We live in NJ they use X all over the place.) It hadn't gone off at all sitting there until all the sudden 1 bogey 1 bar 2 bars 3 bars etc... The strength grew with a forward arrow and I was facing towards a wooden fence. To the left of me about 10 seconds later, a local police car came to the red light and the strength was maxed out, then as he turned the corner it faded away and turned off.
Pretty wild that it picked one out coming down the road from fairly far away not even facing it! I was impressed.
Anyway I've had it for a few days, so I'm new to this but I like how it's behaving so far... My only compliant is the suction cups don't stick to the window for very long.. I guess I try a new set.
