So far these are working as advertised. I can't comment on longevity because I've only used it for 1 day. It does help to keep my purse on my shoulder which is great. The reason for 4 stars is because my hair gets caught on the edges a lot. I'm hoping that will get better but I don't know. I would buy these again as long as they don't come off like some of the other reviewers have said.
