I received the full package quickly and I made myself a joy to unpacking. I began to paste a fixation on a helmet and test the implementation of the quick coupler. I had to return to strength and I galley for the out. Nothing comparable with the original GoPro accessories that place and quickly removed without force, it is the objective. Then I tested the clamping screw and then, surprise, even by tightening, it does not hold, the camera is not fixed around its axis, I can add slices to get a serious tightening . I'm disappointed, it's not a bargain ...
