I just bought a V1 within the past weeks and did a drive through ohio, kentucky, tennesee, arkansas, and texas with it. It's pretty nice. My only complaint is it goes crazy sometimes for no apparent reason (laser detector went off in the middle of NOWHERE, and I KNOW there were no cops in the area). However, it came in quite handy in Kentucky when the damn state troopers were clocking from behind.... nice little arrow pointing to the back, "Ka" lit up, and the thing screaming like mad, with plenty of advance warning to slow down 🙂 Just a warning though: a radar detector is not a 100% solution... alot of state highway patrols and sheriffs offices are now equipped with laser, which are 99.9% undetectable (I rolled by probably 6 of them that the V1 didn't light up for AT ALL).
btw: I don't think Valentine Research has any resellers. You can only buy new units directly from them. You can also usually find them cheaper on Egay...
