Laser Engraving Beam Red Light Indicator with Battery Box

Works as expected but no instructions included. Took a while to find complete instructions online but a good video does exist on YouTube.

Works as it should, it was really tough to figure out, directions were terrible and nothing tells you how to align it, searched videos and very ver few, and not helpful. Once you figure it out on your own it's not bad, but not having anything to show you how to set it up and align it was terrible.

Too expensive for a cheap cost item. And not as accurate or sophisticated you may expect for that price.
