We test drove one this past weekend. My wife liked it as she struggled a bit with the lack of rear view. I can see it helping when towing our camper as I often do this chore by myself with a few trips in/out of the car. My only negative was that it was a very sunny day and the view was somewhat like a TV monitor that is affected by the sunlight directly hitting it (kind of blurry). I also hate that you have to spend thousands on the top of the line NAV since we already have a Garmin that works fine.
