I was travelling in a pack of cars. I have a V1, my friend has a Passport. Mine went off and I slowed down. She somehow zipped by me. A little more than one half mile later I see her jam on her brakes. Later I asked her why she didn't slow down, she replied that her detector din't go off until she was within 1000ft of the cop. It was a $250 on the spot lesson plus any increase in insurance premiums.
My V1 has kept me out of trouble and my record 100% clean. It pays for itself real fast especially with double traps and areas with lots of motion controlled doors.
Of course no radar detector will match the Mother Nature Mk1 Eyeball and the Cranium CPU. Drive smart, don't speed alone, don't stand out, and don't drive like an idiot. Let your radar detector be a tool but don't be dependant on it. Radar is only one way for a cop to catch you. It does no good if you are paced or caught by VASCAR.
