Useful for embroidery, repairs, and "oopsie" seam removals. It collects lint rapidly since the lens is plastic, but I found it worthwhile to wipe off since it let me see so much better than otherwise. I could wish for stronger magnification but paired with my reading glasses it's just the thing. It's a little awkward getting it over your head and adjusted until you get used to it but it repays the learning curve quickly. Recommended.
