Review: 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.
Review: 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.
