I love my hubbub mirrors. I bought 2 so I already have a spare. I think they should be mandatory :). Feel free to quote me.
Should I Wear the Mirror While I Walk?

I have ridden cross-country and logged well over 25K miles using your helmet mirror. When I am walking (no helmet), I often unconsciously look where the mirror is, rather than turn my head. Thanks for providing such a useful product.
