I've used the HubBub helmet mirror for over 10 years, on day rides, week rides and a cross-country ride. The mirror is better than mirrors mounted on the handlebar or glasses frame. I've given it as a gift to friends, who enjoy it. I don't ride without it.
Diane...I received my new mirror...and wore it for my first ride across the new Bay Bridge in Oakland, CA. I LOVE this mirror...stable and it is out of my way while offering a great view of what is coming up behind me.
