I've been on vacation and took a few road trips, I've come to one conclusion, Cobra radar detectors are very popular. From the number of people I saw running radar detectors, almost 2/3s of them were Cobra, followed next by Whistler then Bel/Escort. Spotted no Rocky Mountain Radar units yet either. So far out of those I was able to view I was the only one running a V1. Perhaps it is just that the users of better radar detectors also know how to mount them better making them less visible whereas the majority of Cobra users are just slapping them any which way.
Given this I'd say Cobra is doing a good job of selling cheap detectors (and almost all of the ones I saw were lower end ones). I'd also wonder how many of the people getting burned using a Cobra are the victim of their mounting too. I don't see too many doing a good job picking up laser from behind wiper blades or pointed at the sky. While some were mounted correctly a good number were not.
Just some interesting observations from my road trip.
