I bought one of these the last Wootoff and it arrived broken. The head was snapped off the center tube just above the gear track. It is a relatively thin PVC tube (1/2" inner diameter) and not very sturdy.
It wasn’t worth shipping back or kvetching about so I thought I’d attempt to bodge it back together. As it happens, a 1/2" barbed brass air line splice and some epoxy did the trick. (The air line splice tube cost $4.89.)
The legs are a bit springy so I’d suggest hanging some weight from the center hook thing and using the camera timer or a cable release.
Would I buy one again? No. I’d opt for the carbon fiber one I missed out on this time.
