Query: Hard to use

I love the idea of this... sleek, out of the way for transit butreadily available on the road, protected when not in use. Unfortunately,the reality is a hard to use product that does little to improve road safety.Because of the narrowness of the mirror, it's very difficult to focus on whatis actually behind you with a quick glance. Sure, if you sit there for 10seconds you can figure it out, but I don't have that sort of time when I'mdodging through Chicago traffic!Save your money and buy the excellent Mirrcycle instead.
