It's the cheapest version that I could find on Amazon and elsewhere. I do not know whether other versions justify the higher price. Belief that the most High is not better come along. The holder itself is stable and easy. It is well suited to mounting it on my umbrella holder per thread and use so three flashes on a screen. One should rather use larger screens. (Do not forget, the flashes are relatively far from the screen center and therefore the illumination is just at silver screens not very uniform. While the flash heads of Aufsteckblitze can be rotated, but that does not help much. If you have a large screen and rely on light output has he is ok.)
What I have not like about this version of the extremely small metal buttons to tighten. They are elusive and you can not quite put. But while the flash used even has a decent fixing mechanism is the whole thing stable enough.
