### ⭐⭐⭐⭐⭐ Clean Mirror For Teaching Or Demo
*by B***E on June 8, 2024*

As a university professor I use lots of demo pieces in my classes. This mirror is clean and clear with no blemishes and will work well for teaching my class basic optics. A good buy, at a good price.

### ⭐⭐⭐⭐ Nice mirror.
*by B***D on November 12, 2020*

The mirror appears to be of good quality and true to form for my purpose. The only thing that I didn't expect was that the mirror does not have any protective outer ring or backing. Since I am not mounting it in any sort of optical device, the addition of an outer plastic ring would have been helpful for mounting the mirror on a wall.
