Misunderstanding

Have the part ordered as "2 of Busch & Müller bicycle handlebar mirror for external mounting on the right and left." The result is a Prophete levels (as is now corrected in the title). Have him yet mounted.

Verdict: Well, of limited use.

The long support of the mirror trembles strongly when unpaved roads. I had already 2 times tighten the screws, because the mirror had moved in the wind. It's quite possible that the attachment was not tight enough mounted by me, yet, somehow comes as no joy. Hindsight would be another solution (eg. As with a shorter strap) probably better. But the price was right. For 3 stars.
