I liked the size of this mirror where it fit and where I wanted to put it and not collide with existing mirrors in the location of rear approach cars. There are 2 issues with this is for me. It didn't really give me a view of the cars approaching behind my car like a convex mirror should. The second problem: It fell off the car mirror so I don't have it anymore. It hasn't been on the car long since July so I think it should last at least a year.
