Have bought this adapter to attach a Blackmagic HyperDeck Shuttle recorder to my Schulterrig. Was actually more 'ne stopgap, since the professional versions have all takes too long in shipping. But have to say I am more than satisfied. The adapter came up in the clamp of the shoulder pads, it then vertically the HyperDeck Shuttle. Has everything kept properly fixed, no problem. Unfortunately the recorder was in tight position on the wrong bolt rig, not parallel or perpendicular to the rods, but that is probably more on the thread length and actually st no gripe with the adapter. All in all I was very pleased with this workaround.
