In short, the tripod 525M is great. But nothing more. The joint head CW25 waste of money. Suited to easy to pipperig and not for portrait photos. As the mounting plate is very small, you do not get this with the best intentions on the camera (EOS 7D Canonn) properly fixed. This means that the camera always turns away uncontrollably for portrait photos. In addition to me almost the camera has fallen, because the thumb screw has solved for the mounting plate. Only 2 threads, laughable, but Cullmann was quickly supplied with one replacement screw, unfortunately in the same length. Conclusion: Tripod well, rod end I'll probably throw it away and buy a better brand.
So now after 2 years of use I have to revise my opinion of the tripod. For the 2nd time, the screw wg. defective too little thread engagement. In addition to constantly loosen the fastening screws on the adjusters. Get me probably no longer angry with the long stand around and buy another brand.
