Large fluid horizontally, but vertically catastrophic !!

At an affordable price, this tripod at first glance good assets:
Very large, adjustable with crank
Pretty solid, though some plastic elements may seem fragile
Simple and effective fixing
Good horizontal flow
But its main flaw will back him all videographers looking for a tripod:
The foot is definitely not fluid vertically! Even loosened up, even after a session in the lubricating oil, the tripod does not allow the panorama shooting vertically.

In short, a counselor tripod for photographers, but certainly not to the panoramic video taken ...
