Review on TEH HIGH Diameter Molybdenum Reflector Engraving by Wendy Rodriguez

I just had bad luck with this one. The first pack I bought was missing a mirror and the other two were obviously used as they looked burnt. It's not the seller's fault, this sometimes happens in warehouses. The replacement set I received was properly sealed in individual foil pouches, unlike the first set. There were no visible problems and I wore gloves while working. The first day was the first test of the laser to make sure everything was working. No questions. The second day (after I had all the other updates I wanted) was devoted to testing materials. Again no problems and it worked great. The third day was a production day and the efficiency of the laser decreased. I checked and mirrors one and the second are blown. The third mirror was fine.
