Summary:

It is all smoke and mirrors! As you engrave, debris such as smoke and dust land on your focal lens, building up a layer of residue over time that absorbs laser beam power and can stain the lens permanently. Eventually, this lost power will affect your machine’s precision and throw off your laser settings. To keep your device running at its full potential, we recommend inspecting and cleaning the optics system once a week and replacing the mirrors or focal lens as soon they get damaged.

Great product
Size: 6FT, Color: Black-20W
Added two of these behind the couch in a wood ledge between the couch and the wall. A template will make marking the cutout easier. You will need to make one as it does not come with the product.

Worked perfectly for routing all my wires for my desk. The included tie straps were an added bonus. Now everything is nice, tidy and secured to the back side of my rolling desk.
