It's significantly larger than most helmet mirrors, so its field of view is good. The big advantage of helmet mirrors is that with a small sweep of my head I can see everything behind me.
Does it snap off easily? I am looking for one I can use in the poring down rain. I install my take a look mirror on my glasses but when it rains I need to take the glasses off and then I lose my mirror. Looking for something that will easily snap onto my helmet on those occasions.
