I was on the phone the other day w/ a V1 owner and too my surprise, he told me he thinks his V1 sucks on laser detection. I was totally shocked. I told him I have picked up laser in a semi truck using a V1. He said he had sent it in to VR for repair recently in which I informed him his parabolic laser sensing diode inside his V1 may have a smudge/fingerprint on it and it needs to be cleaned w/ some rubbing alcohol/cotton balls. I still find it odd that a V1 user hates the laser detection of his unit. The car he was running his V1 in was a Vette. Personally, I like the laser detection of the V1 and if I meet up w/ this guy, I told him I will clean his parabolic sensor/lens for him to see if it works better. The guy was surprised that their could even be a fingerprint inside the lens. I told him I have seen this before. Thank god for torx bit sets to check out your units.
