Just one example of how the V1 has the best. My Buddy just bought STI DRIVER and I have the V1 3.872.......Ok so leaving work everyday jumping onto the highway my v1 always goes off soon as I enter the thruway and alerts a K band "every time with out fail" which turns out to be a simple construction sign..... My buddy picks me up from work to show me his new car with the STI mounted high on the windshield, So my buddy hits the gas to show me what the car has going up a little hill on the ramp .. His STI goes off he hits the brakes and I said no no dont worry Its just that stupid road construction sign right up here, so he starts to crest the hill and 300 yards away hiding under the sign is a leo , he's pulls us over, I end up knowing the trooper and get out of all tickets. 1 week later I head up the ramp same spot My v1 gives the same false k band read again, but 4 beeps into the warning there comes a 2 in the bogey counter, so I hit the brakes and slow down and sure **** crest the hill and the leo is in the same spot hiding behind the sign!!...Just gives me that much more confidence in my V1!!!! the arrows and bogey counter is THE BEST!!!!
