Bests & Worsts Reviews from Amazon

I don't know how people ride bikes without mirrors; being able to easily look out for cars behind me while riding gives me such peace of mind. This one offers a good field of view without being too large and obtrusive. My commute to work is on a bumpy gravel road and I've only had to re-tighten the mirror once so far in the month since I got it. A couple of reviews have mentioned buying the opposite side mirror if you plan on mounting it underneath the handlebars, but I've not run into any issues using the correct side mounted underneath.
