The build quality is absolutely fine for the price. Ball head and legs are if solved smoothly and very well locked. Only a small hook on one of the legs is noticed negatively. Turning the center column for ground level photos is very easy, and I can imagine that the plastic lid of the column will break down after a few years. Assemblage of a head is very easy and three bolts is fixed this and then not budge. Also safe and stuck the camera to the quick release plate, which is secured against accidental loosening by using a special lever. Here you have to worry about his expensive equipment, therefore.
The only negative point of the stand is the pungent odor of the foam sheathing to two of the three legs. This should probably protect in cold weather the photographer before the cold aluminum, but I have this cut and disposed of immediately. Especially with outdoor work in all weather conditions and lots of dirt this foam sheathing will be quickly filthy. But still you can use from a manufacturer not expect inexpensive, plastic exhaling. Who needs this so and no pungent smell like, which can not buy this tripod.
Conclusion: The tripod is stable, well finished. The ball head meets the requirements of an amateur photographer wholeheartedly. Five Stars.
