The board is convenient. You have to tighten the screw slightly, so that the camera is stuck because it adheres well. If you do not need the red locking pin, which ensures it furnished camera against rotation, then one must know that this is not threaded. In the description it is to be carried out with a screwdriver. One thinks, turned, for it is a screw slot available. Because you can rotate long. I recommend a pair of pliers.
