I returned them and got the Pyle stands for less money and they are made of the proper high impact non brittle plastic fittings.

The knobs and fittings are made of the wrong plastic, which is brittle and will take little impact before they break, like the one that arrived already broken

the weak point on these is the tightening mechanism, its cheap plastic.

Cheap plastic and came broken

Work as they are supposed to work.

The tripod does not go very wide and starts to collapse as you spread them so the width is limited.
