Very nice mirror.  The size is perfect to stay out of the way and the adjustable side mirrors give great range.  I am able to have it off center  so it's not in the way while cruising, but can still get the full spread of a slalom run.  The clasp is rubber on one side and plastic on the other so it won't scratch your window frame (which was very important to me).  The only small nit is that the clasp has a loose piece of plastic, so if you take it on and off you'll have to be very careful not to lose it.
