I also own the same mirror and love it. The first few days I owned it, I found myself still looking over my shoulder out of pure habit, then felt like a real dork. The beauty of having a mirror on a bike is that you can avoid a lot of debris by riding on the other side of the solid bike lane line without fear of being nailed by cars you never hear coming otherwise. Then just hop back into the bike lane when you spot a car coming in the mirror.
