I bought this product after the other reviews seemed mostly favorable. The rattling however is more then slight and actually concerned me about the security of the stones. This concern was well justified after I woke up and one was missing from my belly ring. A huge disappointment that I got over by have 9 other rings. I promptly replaced this ring with a more securely set one and discovered now (24 hours later) that they are NOT surgical steel or stainless steel as advertised, courtesy of an allergic reaction and the only metal I am allergic to is nickel. I took it to the piercing place to show them in case there was another issue I was unaware of but they confirmed that the material was not surgical or stainless steel and that was why I had an allergic reaction. Needless to say, I am more then upset and waiting to hear back from the seller about their false advertising.
