I have had a total of 3 different Nauticam Flip diopter holders. Each one has seized up on me at the hinge. The first one I broke trying to muscle it to close underwater. Our current 2 are my wifes and I's. Both are suffering the same issue. We were in Lembeh, and I started to swing it open and shut in some fresh water, but it still didn't help.
Is anyone else having issues with this?
Thanks for your help.
