Bike Peddler Take A Look Original Cyclist Eyeglass Mirror Rectangle

I found it to be very secure and have minimal movement due to vibration, certainly less than the mirrors that strap to the handlebars. The way mine is adjusted all I have to do to look behind me is turn my head slightly to the left and glance at the mirror. Closing the right eye helps a lot and your attention away from the road directly ahead of you is fairly short.

I bought one of these, but it came with no directions, no photo of it installed and my husband and I are mystified about how to use the darn thing. HELP!!!!!!!!

I like the mirror a lot. It secures firmly to my eyeglasses. It is easily adjustable in all directions. The sleeves/hinges require a good amount of pressure to adjust. The mirror stays where put, even while riding over rough surfaces. The large square mirror provides a good view to the rear. I find that the mirror mildly obstructs forward vision, but I expect it to be less annoying as I get used to it.

I have tried other bicycle mirrors previously, but could never get the mirror quite where I wanted it. And in trying to position it on my sunglasses, I broke the mount on the last one I owned.
The take a look was highly recommended on the bike forums so I tried it and love it. The image in the mirror is crisp and sharp. The mirror and mount are extremely flexible in that the mirror can be tilted side-to-side and up and down. You can also position the mirror farther from your eyes than other mirrors I've tried - which seems less distracting.
This purchase was a gift for a fellow biker, who loves it as much as I do!

Got tired of the mirrors on the handlebars bouncing around and getting out of alignment.
Mounted this one to the helmet, i.e. visor. Can bounce a little, but, always stays in alignment.
Yes, you are half way to geekdom with it, but, it works. If you have it mounted on the left, try closing the right eye before looking at it. Helps to get used to it.
