It IS a mirror. The writing on the sticker is so teeny tiny, I didn't see it. So, not returning it, am keeping it.Hope this clarifies my error.

I like the way this mirror hooks onto my helmet visor. It's quite sturdy, I'm able to adjust it, and it's high enough so as not to obstruct my vision. The convex mirror, however, is practically useless because it gives such a wide and unfocused view. So, I bought another mirror, the type that hooks onto glasses, removed the mirror from that set-up, and glued it to the back side of the convex mirror. I've attached a picture. Now I have a five-star bike helmet mirror, but, unfortunately, that's not what is being sold. To the manufacturer, get rid of the convex mirror and instead use a larger flat mirror and you will have a great product.

The mirror is small but you can see behind you without obstruction of your forward view.

The overall system worked great, but I'm not sure what's going on with the optics. I've had two other mirrors which showed me a reasonable area in back of me in-focus. I am far sighted so with my glasses this mirror did not work. I was able to focus on it, but it didn't show me a useful area. I ended up getting rid of this and fixing my old mirror.
