The Bracket pivots in three places, allowing great flexibility of mirror placement.

The mirror surface, being chrome plated plastic, is not as even as a glass mirror. Images appear slightly "shimmery". However, this does not make it difficult to distinguish what's in the mirror.

Convex mirror surface gives a reasonable field of vision.
