The sliding plate is indeed qualitatively good but has serious design flaws: The clamping of the quick-change holder can only be achieved with the handle is in the Schlittenkuve, does not fit you on, you look terribly pinched fingers; has happened twice with a loud cry more (does hell hurt). And the slide slip through when you dissolve it and besides horizontal uses - Ade Equipment (well that's ever happened to me).
Well remains to hope that soon Novoflex nachbessert expected, is fortunately a slide of Sirui which hopefully irons out any defects and of course should also be fully compatible with Arca.
