## Customer Reviews

### ⭐⭐⭐⭐⭐ Great mirrors!
*by D***N on January 17, 2025*

These are great mirrors at an affordable price. I have a 130 watt machine. Replaced a scratched mirror #2 with this Molybdenum. What was taking 65% power with LightBurn, now only needs 50% at the identical speed (65% before the scratch). Not sure about heat and longevity as I just installed it today. But had to make this review because of the superior performance.

### ⭐⭐⭐⭐⭐ Great quality well packaged
