Review on πŸ” CNCOLETECH 3-Piece Si Mirror Coated Gold, 20mm Dia, for CO2 Laser Engraving & Cutting, 40W-150W by Amber Perez

Revainrating 1 out of 5

Good price not very good quality

These mirrors and lenses are a good cheap alternative - at least I thought so. The quality is not very good. With rare use and thorough cleaning, they only lasted a few months. Several coatings had imperfections upon arrival: blisters, imperfections. They were quickly replaced but quality is still an issue. The coatings have already deteriorated and need to be replaced again. I really wanted to like them, but I just can't use them anymore.

Pros
  • Material: gold Si coating
Cons
  • I don't remember but there was something

Mirrors are too thick, won't fit in a K40 laser.
