These were the perfect upgrade to my stock K40 co2 laser. Received the product when stated by seller and in the condition it was advertised. Will buy from again.

Great for big laser machine

Muy buena calidad precio ,la mejor elección recomendado

Better replacement for the boss laser. Working great better than the original one that came with the laser.

Great value for a good quality lens. Focus was clean on install. Coating is more substantial than other inexpensive lenses that I’ve tried. We’ll see how it’s going in a few months.

El producto es bueno ,pero la empresa de transporte nefasta y no es la primera vez.

12mm lense is head and shoulders above the one that came in my k40.

Works
