I have meanwhile 6 WT-806, which I have ordered sequentially. I see no reason to complain. I had a tripod that fell to be equipped with a studio flash and fairly large softbox in together. It reached a quarter turn to the nut behind the respective locking clamp to fix the problem. Always bear in mind ... by "fixed" is "going on" ... So with a little sense and not go ran directly maximum tighten (apart from that one then certainly receives a static tripod and alternatively could also weld) ;-)
