It went on the bike easy enough but the bracket that goes on the handlebar is bare metal so I put a strip of electrical tape on it to protect the handlebar. I took my bike out for 20+ miles hit quite a few hard bumps going pretty fast and the mirror stayed put. I really like that there is a "wide" view of the road behind me and I had no need to turn my head to look back. There was a minimal amount of vibration in the mirror but it did not distort the view. Also, the appearance of the mirror is not cheap either...it looks and feels worthy. I will be buying a couple more for backup. So far I am very pleased with the mirror.It's sad that the pre-pandemic price of this mirror was $8.99 and it is detestable the company is taking advantage of a dire situation to make a profit. The pre-discount price listed now is a nauseating lie. Pre-pandemic I purchased 3 of these mirror's for "LESS" than $9 each. I WILL look for a comparable mirror at a lower price if I need to.
