Took me a while and some scrolling down the reviews to figure out how the thing works...
Otherwise, this is a pretty stable stand, I see it as an attempt to emulate the Manhassett while being foldable; On the downside, the size makes it less transportable than most foldable stands. I also have doubts about the durability ; how long will it resist to the frequent frictions between the different parts ...
Not the easiest I've seen though...
