Wobbles like a EntenPoPo with the GoPro

The GoPro 3 in the UW-housing is too heavy for the arm. The wobbles quite rough, because the plastic is quite flexible.
I still have a SjCam SJ4000w. Which is slightly lighter than the GoPro and already has a "The Frame" there. Thus, the camera arm is significantly lighter and the arm wabbelt spotty.

I would buy the part not again, unless you have the GoPro with "The Frame" or SJ4000 or their clones.
Even the Curved-Mount is useless for me because I've had enough. A Flat-Mount would be better. It remains in the end only the 3M adhesive and the small Buckle, Buckles because every now and then breaking it out from.

Now I'm going to order an aluminum arm and see if the what is good. The camera position anyway, is super.
