## Customer Reviews

### ⭐⭐⭐ Dimensions/information is critical to make decisions!!
*by D***L on December 8, 2023*

The mirror arrived today - it is indeed optically accurate. However, dimensions/accurate information are lacking in the description. The mirror is 3-13/16" in diameter NOT 4" as advertised. Also, the back is not flat so how is one supposed to mount it? Yes, it may be 2.5 mm thick - I had assumed that was the dimension at the edge. 101.6 mm is 4" . . . this mirror is 76.2 mm!! Hopefully I will be able "to make it work" for my needs?!!
