Review on 🚴 Safer Bicycle Mirror: EEEKit Bike Mirror, Stainless Steel Lens, 1 Pair Rearview Mirrors for Handlebars by Lance Story

The two pieces of rubber I put in the plastic mounts were the only noticeable differences between this set and the $4 cheaper one. I honestly didn't know its purpose from the description on the internet until the package arrived. The right hand mirror had a rubber liner around the mirror that had to be reinstalled (to match the left hand). These mirrors are adjustable, but they're not high enough to be effective. They had to be rotated so my hands couldn't be seen. They tended to vibrate or move when the bike was in motion, causing judder, especially with small mirror sizes. Clamps and spacers were not very effective in securing the mirrors, which moved at the slightest touch. I still use the left one but with uneven results.
