I still have a Mountain Mirrycle on my hybrid. I like it while riding, but it gets in knocked all over the place, and is really in the way when going through any doors. I tried to not use a helmet mirror for a long time, but eventually did, and will probably continue to. Though I must say, I've been intrigued by drop bar end mirrors, and that Zefal Spy mirror.

My Bell (Citi or Metro, whichever is newer) has provisions for mounting their own mirror, which just snaps into place. It's small, but it's sufficient for me. I also have a Bottle Cap Bike Mirror (helmet mount), and another glasses mounted mirror (cycleaware, maybe?) that I haven't tried out much. I'm not even sure why I have both, or where one of them is. If I ride on the street, I usually use the Bell helmet and its mirror. Recently, though, I got a Specialized Echelon, which is a very comfortable helmet. I need to see how the other mirrors work with it.

After using them, I much prefer helmet mounted mirrors. Or the ones that mount to glasses (the one I can't currently find).
