I am not sure  why these have any negative reviews. They must have improved them because they are super great. I am allergic to every earring. I mean EVERY earring. I have tried every single type. Even surgical stainless steel. Had a reaction with them all. Not these! I got a pair for my very active 5 year old and myself. They have never come off. We shower, swim and do activities in them and they still look perfect as the day we bought them. Oh and they are SO comfortable! If I could give them more than 5 stars, I would! :)
