You are lucky to get 6 months out of the chain before it rusts. I contacted their customer service team for a “lifetime warranty” replacement and I had to fight for another one to get sent to me. They just now added a rule that only one replacement is given if it is due to tarnishing. Well guess what my second chain tarnished in the same amount of time (about 6 months). The whole anti-tarnish properties of the chain is a complete sham. It is just another cheap product that is advertised to be better than it is. It’s no better than costume jewellery.
