A monopod helps because it is stable in one dimension and you hold it
to stabilize it in the other dimensions which adds up to better than
hand holding. A sturdy tripod is stable in three dimensions by
itself. It seems like this trek gadget only gives the impression of
stability.
Many of us never use the tripod extension because of the instability
it gives. Mass plus an arm makes a pendulum. This gadget is like a
tiny tripod with a huge extension, two major sources of instability.
Not the best idea and if you grab the camera to damp the vibrations
there is no point to having more than a monopod.
The little tripod part is so small and the extension so long that you
would have a perfectly level surface to use it on to prevent it from
falling over. If you let go of it the smallest gust of wind would tip
it over. Any imbalance due to a even a modest lens shifting the
center of balance away from the tripod socket would just make these
problems worse.
Even aside from this if you consider how old photography is and that
in practice photographers have settled on monopods or tripods, it is
probably for good reason.
