Actually haven’t used it yet. I bought it to use on my sewing machine, great for following straight lines! I’m sure there are other uses for it

Very easy to use. Think the quality is good however I think the price could be lower.

Appears to be adequate, haven't used it yet, but did mount it on an old gooseneck lamp so it should be easily used. My purpose is for aligning machine embroidery, so the cross hair attachment is great.

I bought this item last year and it doesn’t work. The light is not bright. So I bought another one. This one works that I just purchased I’m sending a picture of the laser light to show you it isn’t bright at all. Can’t see anything with it. It’s a piece of junk.

This works well when lined up. It is too easy to knock out of alignment and getting the alignment exact is tricky. More or less content with it.
