I've been using the tripod for about three months now and I'm basically quite satisfied. I have no doubts about the holding power of the ball head, among other things, and so far it has held my cameras with the use of a long rail - which significantly increases the load from the lever - without any problems. However, the system quickly arrives at macros that require fine adjustment of the position its limits. But you have to see that in relation to the price and therefore only a limited point of criticism. Since I do a lot of macros in nature, I often have to convert to under-head mounting to get close to the ground (folding over would also work, but limits the use too much) , which is now almost impossible. The center column is clamped using a union nut with a plastic cone underneath. where fine adjustment of the height is not necessary, definitely a good tripod for the price. Not recommended for people who change the position a lot and people who want to use the center column adjustment often.Update: The manufacturer definitely deserves great praise for its support. Answer came the next day with the request to isolate the problem. In addition, there are photos and a small video. For this customer service, I am increasing my stars to 4. More is not possible, since the adjustability of the center column is not usable for the macro range. Answer came the next day with the request to isolate the problem.
