Metallic tint cuts the range of any radar detector not just the V1. But since metallic tint is usually not applied to the front windshield, it's a half-truth that the V1 is affected more. But a less sensitive antenna is still better than nothing at all, which is the case with other detectors.
My vote is for the V1. I haven't been pulled over ever since I got one, even though my speeding habits haven't changed a bit.
