Review on Adjustable Bike Rear View Mirrors by ZOSEN for Enhanced Handlebar Visibility by Mark Hart

I really like what the mirrors are designed for – moving up from the steering wheel and giving a clear, full view of the traffic behind you. Although it's very tight with pliers, it needs to be tight enough to stay in place. After about a month of use while driving up a sidewalk ramp, the impact broke the cocking locking mechanism. I prefer a flat mirror to a convex one. show a larger area. I need a correct perception of distance to the cars behind me.
