Review on 🌩️ Cloudray K Series: Complete Set with Head, Mirror Mounts, and Focus Lens for Laser Engraving/Cutting Machine - D20 FL50.8 Mo Mirrors for 2030, 4060, K40 by Barbara Simmons

The quality of the product seems to be very good, the aluminum has scratches from processing, but these have been touched up with a blue felt-tip pen. Well if you're thinking about getting this for the K40 it's going to take some work to install. You will need to drill additional holes for mirror 1, longer M3 screws for mirror 2 and a new mounting plate for mirror 3 and head. I'm not saying it's not worth it, but given the information upfront, I may have been looking for something directly relevant. They give you all sizes so technically they're not lying but it's quite a bit of work especially making the head mount,
