Have been using my mirror for the past several months and, upon reflection, think it is one of my best purchases in the past year!
He’s had his for 10 years!
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.
