This Optex tabletop is a reasonably sturdy device, suitable for small-to-medium mirrorless cameras and DSLRs. Not terribly tall- the maximum height is about 27cm with the column up- but with a wide base and a centrally located suction cup for, I presume, extra holding ability on glass. Before you get any ideas about this being a self-contained window mount, that suction cup is just a helper, and it's not close to big enough to support the tripod, let alone the tripod with a camera on it. In excellent condition, with a three-way head.
