I purchased these Gold heart studs about 3 weeks ago for myself, as a vacation alternative to the diamond studs I normally wear. I have very small earlobes and these fit perfectly. They stayed in place with no issues. The backs stayed secure without loosening or falling off through showering, swimming, zip-lining with a helmet on, sleeping, etc. I know others had issues, so either they changed the style of the screw backs or user error? Happy with this purchase and would recommend.
