Fluid head shaky at the start of the swing

Pro:
1. The tripod looks beautiful.
2. It is not difficult.
3. The level is good enough.

Contraindications:
1. The fluid head trembles at every start when I wave to one side to other.
2. The water level is too small.
3. Mussmann keep the tripod to a hand when you move the fluid-head, as the whole building is no stability in the movements.
4. The quick release plate is not so easy to assemble.
