Good strong product, plenty of mounting locations. It does move the handle up a bit but not annoying. A very strong connection so you don't worry the body will fall off the handle.
It could be used as an adapter to mount the original top handle of Canon C100/C100 MarkII/C300/C500 to the camcorder. It features quick release and detachment. It is very useful!
