I just received my first tripod, and I have not been disappointed at all, the bag is in, the structure is perfectly stable and solid rather I find them correct bubble levels on the maximum height of the tripod nothing complaints, Amazon thought to people over 1m80 with rising central column.
Everything remains fixed with clamping referred, no worries on that side. (Do not force it like crazy course).
The only problem I can find, as an amateur photographer, is the fluidity of the platform. Indeed there may be little jerk on your videos if you rotate the device.
