I have purchased my second DJI 2 camera after the ribbon broke on the first one and the oring gave out the first week I owned the DJI.  I've owned the second camera for 2 weeks now and the oring on the second camera won't hold the camera assembly in place again.  2 thoughts:  First, I think I have to firgure out a way to tie the camera assembly together so I don't lose the camera in flight and 2) This seems like a clear defective design that DJI is no doubt aware of and I wonder if enough users experience this and talk about can we get DJI to make good by replacing these defective assembly's.

Can you post a photograph.

By O ring, do you mean the anti-vibration mount? There should be some anti-drop pins with it, or if not just loop a cable tie loosely through the middle.
