Has anyone else experienced this problem? Due to the flat plastic on flat plastic of the tab system, the mound and housing don't clamp well. I find myself cranking on them with a good bit of force to get the camera to stay still. Doing this has broken my tabs off the housing. I modded it with a hole drilled through a piece of aluminum angle, epoxied to the housing, of which I sanded the nubs of the rest of the tabs off. I drilled out one of those plastic pieces that turns the camera 90 degrees, put a 1/4 inch bolt through it, put a lock nut on the other side, and I was back in business.
