The glass shattered.

Well, running off-road, i hit a bump and my head went directly into the corner of it and cracked the glass

The glass broke after 3 days of being installed.

For something that is meant to go fairly close to where someone's head or helmet is going to be bouncing around I expected this to be plastic or poly-carbonate, or at least much stronger glass

VERY FLIMSY GLASS

The first time that I got in the car, my helmet touched the end of the mirror and broke the glass
