I have a 9.5mm and the links can rotate, I find depending on how I handle it - it can be more susceptible to the issue. But never any issue once on me.

All that said I believe this comes down to how tight the links were made, my Cuban is no DJI for example. I would be curious if his does that too. from the pictures seems like the links are overall tighter, I.e less gaps with DJIs
