Have I bought the tripod just before my winter holidays (25 January 2012) and was initially very pleased. I have my GoPro draufgesetzt until I noticed the head (as here described often) is not stable. Had there but a good idea. Took me nuts and it between the screw head and the plate where the camera or the attachment for the GoPro Depends placed. Thus, the head was stable and there are some accessories are indeed parts in GoPro, I could attach the camera so that it was still very mobile. But after a short time I realized sadly that the whole head of the tripod unstable so was the part of the plugs directly into the pipes / Verlägerungen. Meanwhile, these drops and also the individual elements / tubes / extensions have fallen apart. Thus, the Sativ has become unusable. I am therefore very dissatisfied.
