I have a NA-RX100II housing on a flexitray II + handle and one Inon Z-240 strobe on each handle at the end of (5"+8+) arm assembly. Today I took my rig in the pool to familiarize myself with it, and found that the right handle was getting loose over time. Has anyone else experienced this? It's possible I didn't tighten the screws enough. On the other hand, I need the handle as far away from the housing as possible to manipulate the buttons, and the handle is just held by those two small screws, so I'm worried.
