Gee,
I have a 'Cat Eye' bar end mirror and won't leave home without it . I do have
to move my left thigh a bit but it is now second nature. Mine did vibrate a bit but
the mirror was loose in the housing which super-glue fixed. I used clothes pins as clamps
at three points on the mirror and put drops of glue beside them, welding the mirror to the
housing. No more vibration.
I have not tried any other types of mirrors.
