I have had one for 6+ years. I fragged it a couple of times and a buddy has a piece in his system for atleast 2 if not 3 years now. I think that shipping is hard on these guys because they are so heavy. Think about it - if you ship a stalk of branching hammer it's light, now encrust it on a rock and ship that, the rock is heavy and can really mangle the coral - leading to infections.
