Review on Mordely Bike Mirror - 2PCS Adjustable Handlebar Rear View Mirrors for Mountain Road Bike Bicycle & Electric Motorcycle with Wide Angle Acrylic Convex Safety Mirror by David Gibbs

These mirrors fit my electric scooter well. They were the only ones large enough to give me an idea of what was behind me as I drove. Unfortunately, because the mirror can be moved but doesn't lock into place, it makes a high-pitched buzz while driving, which gets louder and louder as the speed increases. While the mirror must be designed to snap into place, the designer obviously didn't invent it. Another unfortunate aspect of this mirror is the mounting fixture. It's not the worst I've used and it does the job, but it does loosen up over time and I have to tighten it every few days or it falls off. So on the one hand I have the safety advantage of not being able to turn around, which is behind my left shoulder, but I have to deal with extremely annoying noise so it's generally acceptable.
