Review on BriskMore Bike Mirrors - Set Of 2, Bar End Rearview Mirror For Bicycles With HD Glass Convex Lens, Enhanced Safety For Cycling by Ken Kowal

The Glass mirror makes it far clearer than any other bike mirror we've owned. The mounting system, however, left a lot to be desired. We bought two and I had to learn on the first one that the Hole in the end of the hand grip has to be very close to the diameter of the mirror mounting shaft. You can not force the mounting shaft into an undersized hole in the hand grip as the rubber cover on the shaft peels back and the individual pieces fall apart. I enlarged the hole on the second installation and it was not a problem but in my opinion the mounting system is poorly designed.
