### ⭐⭐⭐⭐⭐ It's a great mirror!
*by S***S on April 10, 2025*

It's great, I actually use it for a spin station, it's that perfect. That's actually why I bought it...LOL.

### ⭐⭐⭐⭐⭐ Well Made
*by P***S on January 18, 2025*

This mirror provides accurate reflections (considering its concavity).

### ⭐⭐⭐⭐ delamination around edge but still functional for my purpose
*by F***N on May 26, 2024*

I purchased to use as a beam spreader from a point source It works in that appication but certainly is not "defraction limited optics'. Took off one star as there is some form of de lamination in the outer edge.
