Just like OEM.
These are the same cheap lenses that came with the K40.Works kust like the OG. Good as backup mirrors in case you need them.I am ordering the gold mirrors next

Don't waste you money!
This is a complete piece of junk! I installed all three mirrors without touching the reflecting surface and all three broke into pieces after a short period of low power use in my k40 laser cutter.

they're okay, but not fantastic.
These are a direct replacement for the K40 series laser. they're coated glass, which means they're very delicate. just like the originals. If you're looking to upgrade, this isn't an upgrade.

These were great for replacing the mirrors in my K40 laser

I wish I could give zero stars
You get what you pay for. I have a full spectrum 40 watt laser and opted for these because they were prime eligible. I installed and cleaned them. Lined up them up and began a first cut , then I heard a pop. Initially I smelled something burning, so I really got scared. I began to check these mirrors and bam...... broken into pieces!!!! Save your time and money

Broke at first use, all three
This lens broke in 4 peices on first use at 15% power on a the K40 40 watt laser from the laser beam alone... all three. Total Junk.
