Review on Hafny New Handlebar Bike Mirror - HD Blast-Resistant, Crystal Clear Glass Rearview Mirror - Adjustable Rotatable Bicycle Mirror, HF-M902RB-FR01 (Anti-glare Blue Right) by Jeremy Jackz

I installed this on my Specialized e-bike to replace a stock mirror that had the screw connecting it to the mirror cut off. The standard mirror had a very rigid metal shaft and was firmly attached to a round mirror. It was very good until it broke. The new mirror was easy to fit and could be adjusted to give a good view under the left handlebar (like the original). The mirror is very clear compared to plastic lenses. The only downside is the vibration caused by the connection between the mounting arm and the mirror itself. I think the vibration would decrease if there was a stronger connection between the hand and the mirror. I can simulate this by holding the mirror hinge while driving. This isn't a huge issue though, which is why it still gets 4 stars for quality, value and ease of installation.
