I've had my Mirror now for almost 3 weeks. I think its a well thought out device that does exactly what its supposed to do. However i've had a few interesting observations w/ the mirror, none of them take away or are a negative, but its worth visiting.
I live in Houston, the city of overpasses, and pretty much every major road has a highway or overpass above it. So I'm traveling down 59S towards Rosenburg and my mirror alerts 5 or 6 times during the 30 mile trip that there are "redlight camera ahead". I watch the closing distance each time and the chime sounds. Obviously there is No redlight camera on the highways, therefore, BELOW me on the street level there is a red light camera.
My passenger stated a couple of times, since my garmin GPS has a altimeter function why doesn't the mirror--food for thought
