Si Reflective Laser Mirror

I used these to replace the mirrors on my at-home 100W CNC Lasercutter. This machine sees a maybe 2 hours use a week, and I've had it a few years, and noticed that the existing mirrors needed to be replaced. The new mirrors were easy to install and instantly improved the consistency of cuts. I did a recalibration of the mirror angles prior to use, which doubtless helped, but the machine is working like new again. I can't vouch for the longevity of this product, I just don't know how well they'll stand up.

Works great. They have been holding up just fine. I use them kn my k40 and get muxh better cutting. They are thicker then the standard k40 mirrors, but they do fit just fine.

I got these to replace my cracked stock mirrors on my K40. These were drop in replacements and work great. Note: on the K40, if your mirrors keep slipping and need re-aligning, just generously dab hot glue on the screws once you have everything aligned. I used to have to re-align my mirrors very often but after I put hot glue, I haven't had to touch them at all in the past several months.

Mirrors were a perfect fit and came packaged very well...foam package, wrapped, and plastic protective cover over the mirrors. Cheap little upgrade over my OEM mirrors.

Buen producto, para mejorar, se pela el color amarillo, pero queda color natural y sigue funcionando

I took my stock mirrors out of my chinese good ole k40 as part of my slow upgrade process because of finances. Disappointed my dsp completion wasn't more than I expected, I know lasers and had just tried to clean mine often because they looked okay. Then I put these in... HOLY ****! It made my machine capable of what I'd hoped for. From epilogue to this thing... i now gotta get a lens but the mirrors have been the biggest quality change yet. Worth every penny. No I'm not paid for this, they're just that great! Thanks guys. Well packaged!

Packaging was the only compliant the sealed packets where good.. nice seal, the plastic case was awful taped on it to keep it closed tried to put my old ones back in them for safe keeping nope.. will put else where. Mirrors where great no scratches or spots!!! nice upgrade and I still have my od ones for an emergency Bought after reading a legit review about a pin board.. thanks.......Christopher

Gives my K40 Laser the extra power it needs. The mirrors are much better than what came with my laser and allow me to cut and engrave at a much lower power level which gives me piece of mind knowing I’m saving a little money on my power bill and also that It is a little safer engraving at lower power.

Great product delivery extremely fast
