Review on 🔍 SHINA ZnSe Precision Laser Cutting Lens by Darion Wooten

I bought two of these lenses and both had a matte finish and were new to lasers. I thought maybe they should be. However, when I put them in the car, they didn't cut at all. I spent 2 hours checking mirror alignment and tried different focal lengths but they never got them to work so I gave up. As a result "I WILL NEVER BUY ANOTHER LASER LENS MADE IN CHINA"!
