Review on Handlebar Rearview Reflectors Adjustable Rotatable by Daniel Fung

I replaced some round mirrors with them, thinking a larger oval would give a better view. There was an error. Although they are easy to install, they are useless as mirrors. The mirror is flat rather than convex, perhaps due to the shape. A flat mirror offers such a limited view that it is dangerous. In addition, the incessant shaking and tiny speck you see is blurry. These mirrors wobble, probably due to wind resistance. I've tried tightening them and adjusting them at different angles but nothing stops the shaking. I can use other mirrors on my bike and they don't wobble as much as this one. I've reviewed over a dozen types of bike mirrors and these are the worst I've come across. These mirrors are really easy to assemble. I have Velo Ergogel grips and they fit right into the end of the handlebars with no problems. The installation takes a few minutes. I have tried these mirrors both during the day and at night. They are unsafe and completely unusable. I cannot recommend them at all.
