My personal experience with this mirror is the following:
“Upon first usage, I immediately noticed that I had a better forward field of view. I looked at my shadow, and noticed immediately that I did not have a rod pointing forward from my helmet.
I was also reminded of years past when I could enjoy the scenery without a big mirror image to my left. I am able to view rearwardly approaching objects and their trajectory (very important).
The magnetic attachment allows for easy detachment, but I often leave it on the helmet as it has less of a tendency to become damaged since it is so small.
Detachment requires merely a wedged fingernail between the magnet and the mirror body. I have no reason to return to a larger mirror. In my opinion, this a very adequate and valuable device.”
