The build quality and stability is very good indeed. The problem, however, that the lower base of the dovetail guide is thicker than the ARCA-SWISS-standard and therefore not drive with the Gitzo ARCA-Swiss adapter GS5160CDT usable. With the heads of the Sirui L-rail is easily usable.
Addendum of 12/23/2014: The track is not suitable for the Olympus OM-D E 1, because the strap mount on the camera body collided with the bow of the L-rail and the L-rail therefore can not touch the camera body side.
