I'm very pleased with this product so far. I received a locket as a gift, but it had no chain with it, so I initially spent a LOT more money on a shorter chain at a brick and mortar retailer, only to have the chain break within two weeks of what I considered normal but not everyday wear.  Since they couldn't replace it, I turned to Amazon (like I should have in the first place), and found this gem.  The links on the chain are beautifully delicate, which is a great compliment to the locket I wear on it.  It seems quite sturdy so far- I bought the long chain, so I don't have to clasp and unclasp it, I can just put it on over my head, which probably helps, but it doesn't look like I'll have any problems with it and it feels well-made.  And when they say 30", that's truly what you're getting- it's a nice, long chain.  For the price, it's an absolutely unbeatable deal.
