to make it short: the suction cup holds bombproof, the GoPro quick release is totally cool, because I now have to unscrew not annoying now and then the Cam, but screwing is not ideal because the upper screw lock to the camera holder can not really notice , at least not by hand. As a result, looking at the camera continues to adjust, although it should be rigid. one must consider whether it is sufficient for the claim, depending on the application.
