Review: Great replacement part for my laser cutter - Used this to replace the 6 year old lens on my 100W CNC laser which looked a bit cloudy. Cut mostly balsawood, plywood, and magnetic rubber. Could not believe the difference in cut quality with the new lens, I guess I should replace it more often!
Review: They work soooo good - I like the size of the pin point you can get from the laser. This is on my k40 Chinese laser and I use it all the time and this was a good choice for me.
