Review title: Not a good mirror when used with glasses
Product review: Not sure about all the glowing reviews here. For me, this mirror is no good at all. I do not have a bill on my helmet so I do not know about that config, but clamping to my eyewear does not work. I have tried every possible angle and combination, but mostly I am looking at my shoulder and only with strain can i occassionally see something in the road behind me. Quite useless
