Weefine external HDMI cable reliability on the long run.

Hello, 

Underwater cables are known to be fragile parts (I work in the marine industry) but those little video cable we use between housing and monitors seem even worse.  I am using a Weefine WED5 on my GH5s. I mainly bought it for its compactness but immediately noticed the external video cable is thin, thinner than the Nauticam ones I have. This made me suspicious on the long run regarding reliability. 

So the cable finally died after 60 dives (and still under warranty). Another diver told me he was already in its third cable and the reseller told me Weefine has issued a second generation cable. 

Has any of you noticed those cable are particularly fragile ? And do you know if 2nd generation is actually better ? 

Thanks !
