Helmet mirror really works
"The 3rd Eye mirror with it's larger mirror size works very well and is relatively easy to mount on your helmet and adjust. It is far better than the blackburn helmet mirror which has a much smaller mirror surface. On older style helmets, it's hard to find a completely flat spot that appears large enough to fit the whole mounting surface, but don't worry, the whole surface does not need to contact the helmet to be secure. On the newer, smoother surface helmets, this should not be an issue."
