Even while unpacking we could see that the head sits slightly askew. The thread of the head which is screwed onto the threaded rod extendable was already torn. Did the whole thing again unscrewed, this plastic-chips were dropped from the thread :( Why is this part that is exposed here is clearly the greatest burdens of so thin plastic? The linkage looks very valuable, can not imagine even heavier cameras to put it. The joints (z-axis and vertical axis) act upon pivoting with much resistance to. Here you have to hold on slippery surfaces the tripod to prevent it from slipping.
