Review on 🚴 PChero Bike Glasses Mirror: 360° Adjustable Wide Angle Rear View Mirror for Safe Mountain/Road Cycling by Victor Houser

I use this mirror every day when I walk our big dog. Cyclists and joggers approaching from behind are all too easily caught off guard: on a busy road, they can't be heard at all. It can be easily attached to both sides of the glasses. It also attaches perfectly to the peak of a baseball cap. Once fitted, the mirror is easy to adjust so that I only have to take a second look in the mirror as I walk to see if someone is approaching from behind. When someone walks, the dog and I leave the sidewalk on the lawn to let people through. I no longer have to stop and turn or try to turn and look around while being pulled by a 100 pound hound. Definitely recommend.
