The boom arm looks suspiciously like http://www.amazon.com/gp/product/B00DY1F2CS which i bought a while back and is pretty attrocious.
The arm required replacing the screw connector after just a few weeks and requires frequent tightening of the nuts and bolts on all the hinges to maintain any structure whatsoever.
izzy411Very similar, but I have no had the same issues you experienced with your mount. The tension screw has not been replaced, nor adjusted once since my initial setup. The springs provide ample tension and support. No issues here, sorry your experience hasn't been similar.
