MEACHOW Bar End Bike Mirror - Crystal UHD Automotive Grade Glass Lens for E-Bikes & Motorcycles - Scratch Resistant, Safe Rearview Mirror (Silver Left Side ME-022LS) - Perfect for Cycling Safety & Urban Commuting

The best of Many!!! Finally a mirror that works to my expectation! I tried at least 4 others and the performance was poor. This is simple in design but works because I can see behind me perfectly and I am on an electric scooter with short handlebars. Mirror can tighten to prevent misalignment.I do not usually write reviews but this product is a home run for 24 dollars.I practical and functional mirror is essential for safety reasons. I am constantly monitoring the traffic behind me.Again, we'll done!!!!!!!Update - there may be a small rattling sound from the mirror. I tightened it and sound is lower. I will monitor the sound and update soon. I am not 100 percent sure that low buzzing noise is from mirror but it seems like it. I will try to reinstall mirror and see what the result is. The mirror is still worth it, even if there is low noise. I will update as I continue to test the mirror. I still recommend the mirror for purchase.My conjecture is that the small internet pieces that are tightened to expand inside the handlebar can vibrate creating low noise. I will try different mirror installations to discover if the procedure will remedy the issue.Stay tuned for update!I bought another and installed on my mountain bike with no issues or vibration.My scooter may have excessive vibration. The mirror works great on my mountain bike!
