With them crazy suction cups I prefer the visor mount. The suction cups appear nice but I'm sick of them falling off and even better the visor mount is less visable. I have talked to the techs at V1 and they agree that there is no range difference between the visor mount and the window suction mount. Living in a crime area in California, its so easy to take off the visor mount. What does everyone think about the range of the radar detector difference- and what does everyone think about the visor mount? I tend to love it! I can clip it on my BMW and then my Cadillac.
