We have had a few of these fins breaking. Scuba pro has us destroy them cut them up and send them a photo.no need to send back to them for replacement.Only telling you what I saw. I have no idea what the policy is for busted fin return to Scubapro--I'm a patron, not a dealer, but these were definitely going into the garbage can. I suggest you call Scubapro and find out what their policy is. If you really want to call my LDS in Japan, feel free to PM me. Hope you speak Japanese. And yes, the orange ones were definitely Gorillas, so you've now heard of them failing.
