As long as we're revisiting this thread I'll add what I noted before - my Chuck Harris mirror survived my December crash nearly unscathed.

I landed on the left side of my face, just off center so my nose was spared, and skidded briefly. The grinding noise I heard turned out not to be my new helmet - which didn't even touch the ground - but my mirror and sunglasses.

The glasses were a loss. The mirror itself had a little scrape on the plastic backing. The stem was slightly bent, but easily bent back - bending the stem is how you adjust the mirror anyway. And the soft coating on the mount was scraped off. Not sure now whether it was shrink tubing or the liquid dip stuff - either way, I haven't got around to replacing that yet, just have a bit of duct tape over the edge.

As I said in my earlier post, if I broke that mirror, I'd really have to be trying. I tried pretty dang hard that time, five stitches in my face, but the ground was no match for that mirror!
