Review on 2PCS Bike Rear View Mirrors - Adjustable, Rotatable Handlebar with Wide Angle Convex Mirror for Mountain, Off-Road, and Fixed Gear Bikes by Rich Montgomery

Used on my old Raleigh mtn. Bicycle. As the title suggests, the mirror is very easy to install. I actually installed it on my bull horns and it didn't interfere with the handlebar grips. It holds up well on both roads and trails without losing its set position. Its wide viewing angle is good enough to see nearby drivers and other vehicles. However, I would like the mirror to provide more rear vision (probably not as convex), which would be a big help on roads where cars are approaching much faster. I hate the thought of not being able to spot a distracted driver coming from behind without having enough time to swerve to avoid a crash.
