I got one as well...haven't tried it out yet.
I recall you're not really a fan of mirrors, so I don't know if you'll like this one or not. Tried it this morning and it works. I have to fiddle with it a little more than larger mirrors -- the small size means precision is important -- but once I get it dialed in I can see behind me just fine.
I got a pair of them in the mail, too. Never been a fan of mirrors, but this thing is small enough that I hope it doesn't annoy me.
I asked Joanna what she thought of the Messenger Mirror: "On a scale of 1 to 10, how dorky is this bike mirror?""Umm, about a six?"
I have bough a mirror which you can attach it to your glasses back in 1996 for $8.99 and I am still using it.
