From the solid metal parts that are all connected to ball bearings I was immediately convinced. Only the rotation around the horizontal axis at the ring center bar was a bit too stiff. After an email correspondence with the supplier "Happiness Express" I was offered to solve the side screws of shipping a snap ring pliers. For reasons of time I bought myself unceremoniously such pliers at the hardware store and began to solve the very stiff special screws. It turned out that not these screws, but the outgoing from the handle V-shaped enclosure of the rotating ring that caused the problem. With a bit of pressure by opening a between pushed Wasserpumpenzange I could "V" extend a millimeter, so that after assembly now everything is delightfully easy to move. My with little more than 400g quite lightweight Sony Handycam let austarieren quite easily clean using sample videos on the web after removal of all weights and only slightly off the center rod. By weight and by further extension of the rod has to be used with this tripod good opportunities also significantly heavier cameras. However, you should be aware that cameras with less than 400g weight are not suitable for the tripod. Here one should rely on lighter Steadycams.
The only minor problem to the tripod, the optional-to-use 1/4 and 3/8 inch thread screws which can be tightened by hand not, but always a coin (or a thick screwdriver) need.
Due to the otherwise perfect processing and flawless functioning of the now comparatively really very reasonable price the full marks.
