I have tested this with heavy microphones, with lightweight microphones, with all imaginable kinds of "Zoom" and pickups with broadcast quality. And I have tested it on old kitchen tables, modern desks (height adjustable or not), in hotel rooms and in all possible places in all conceivable studios. It has never failed, it is stable (an annoyance with any other stand och rod) and robust.Doesn't leave marks on any surface.
It is not the most aesthetic design, but who cares - it's so easy to hide away. Care must be taken when installing it (mind your fingers), but that goes for more expensive rods also.
I recommend it highly.
