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 *by B***N on December 5, 2021* Upgraded a customers Laser cutter from Si mirrors. These will be easier to clean and maintain. ### ⭐⭐⭐⭐⭐ Great mirrors.
