I have owned both the X50 and the V1. At times I miss the X50 (was stolen), but I love the V1 at the same time. The arrows do actually come in handy at times, although if you know your detector enough they are not really necessary. You can't go wrong with either one really, they are both real, real good detectors.
I have wondered about the veil coating as far as if it changes the color (tint) of your headlights and license plate, and how long an application stays on (regarding washing car frequently)?
