Has anybody has this happen? My wife bought two DP aluminum billet mirrors for her bike and installed them a few weeks ago. Today, while riding on the freeway, the mirror unexpectedly flew off -- just the glass, nothing else. She wasn't able to pull over, obviously, so now the glass part of the mirror is gone. The housing is completely intact, but we noticed there is no glue or anything remaining. Does this sound familiar to anyone out there?
