One of my buddies got one, it was pretty loose and squeaky during adjustments compared to the RRS Vyce I have. It held the gun fine...but the RRS is a much nicer part looking at them side by side. You can gradually release the RRS since it adjusts a lot smoother, where the Leofoto kind of bound up and dumped all the tension at once. Visually they looked to use the same mechanism and I'm sure Leofoto tried to copy the dimensions of the parts they copied 1:1, but quality matters.
I elected not to cheap out with $15K of stuff clamped to it 5ft in the air.
