The product was no manual.
The crank by means of which a tube on which the camera recording rests, is moved out of the tripod making, as well as the adjusting screws, a cheap and hardly durable impression. That the mother (also made of plastic) which has the task to lock the extended from the tripod pipe, overexcited with the slightest tightening, solidified this impression.
The product affects me badly processed and unsuitable, permanently and securely to hold a camera and adjust its position finely.
