The B2-ball head makes my DSLR camera quickly and precisely in position and keeps it without slipping. So he works exactly as expected. The problem described by other reviewers with the stiff Panorama plate I had. Upon closer inspection, I noticed that the locking of the ball head must be on the tripod right in the center around the thread. My tripod was outside, so that the center is slightly lower on the receiving plate rubber padding. If you turn now head to the plate, so you caught not the center, but the freely rotating panorama plate against the rotating mechanism of the ball head. With this a turning nothing. A thin washer in the center has again taken care of the right flange and for a freely rotating panorama plate.
