    Unless a handlebar mirror is much larger than a helmet mirror, it will be
    hard to see out of.

    Some people seem to like them, but more people use head mirrors, the
    advantages are less vibration blur and greater field of view with head scan.

    For me, yes. I had trouble focusing my eyes on the helmet mounted.

    Vibration is a problem, I reduce it somewhat by wrapping the arm with friction
    tape and cotton string, it helps some. A flat mirror still vibrates too much to
    be useful a lot of time, I use the convex one.

    The Bell brand comes with a mount designed for handlebars. I put it on my brake
    handle with some electrical cable ties, like it better there.

    No, they're considerably worse.

    Handlebar-mounted mirrors are so far from the eye, and so subject to
    vibration that they must be convex to work at all.

    Convex mirrors distort apparent distance, and also require you to
    re-focus your eye.

    Helmet- or eyeglass-mount mirrors are close enough to the eye to give a
    good field of view even though they're small.

    The effective field of view is greatly enlarged by the fact that you can
    "scan" by turning your head from side to side. They actually give
    better visibility than all 3 of the mirrors of a typical car.

    They are not subject to as much vibration as handlebar-mounted mirrors.

    Because they're flat, you don't need to re-focus your eye to use them.

    Head-mounted mirrors do take a bit of getting used to, typically a
    couple of weeks of regular use.

    Obviously a personal preference. I am right eye dominant so a helmet /
    glasses mount mirror needs to go on the right which doesn't make much sense.
    I've used the Third Eye barend mirrors on drop bars for at least 10 years
    and wouldn't use anything else. Innocuous, very little vibration, as easy to
    use as drivers side mirror on your car. Keeping track of the behavior of
    overtaking vehicles is second nature.

    Note: Mirrors on little stalks don't work. They vibrate way to much. Are
    easily damaged.

    [of barend mirrors]

    I tried one when I still had DT shifters; it was hopeless. The vibration
    makes it hard to see anything, and the mirror is always being pointed
    where you don't want it. The real danger would be in assuming what you can
    see in the limited FOV of the mirror is all there is.
