An hour ago I got the part of Amazon. Unpacked and with GoPro 3 and my Panasonic HDC SD 66 tested. When one's hand, not only has his thumb and can see reasonably is the tripod in a minute two cams balanced. Go during normal and panning the image remains extremely quiet. What more can you ask for 40 euros more? The quality is top and it looks high tech made. Also, the ball joint is running absolutely clean. TST's.
