Query: I won't ride without it now.

I have had a handlebar rear-view mirror for years, but it got bumped out of alignment all the time, and I would have to turn and twist to actually see what was behind me. Several months ago, I bought one of the "other" brand eyeglass-mounted mirrors, the one that's made of black plastic, and I think it blew out of my bike's seat pouch on the highway. This one is SO much better. It's a nice, large viewing area (I have the regular size, not the small), and because it's frameless, it doesn't draw my eye to it as much. It's also quite a bit stiffer than the plastic one so it grips the frame of my glasses tightly and really holds its position once I've adjusted it. I feel much safer on the road now because I can see what's behind me with just a flick of my eyes.
