This framework is the only option to be able to mount without a HOUSING GoPro. Often you just need only one mount for the GoPro, without the camera would have to be really protected. In addition, this simple framework is super.
A small drawback is that it does not (at least not with the LCD Touch) compatible with backpacks. Could possibly work if you cut away the surfaces, even the back.
Processing / material is poorer than with GoPro, but still OK.
