Hello, I'm excited. One processing as Arca, Novoflex, Foba and other high-end manufacturers. The The rotation function / Pano runs smoothly like a Arca Monoball for 500 euros. The clamp holds bombproof. The supplied adapter plates is extremely processed accurately and extremely clean. The intelligent disk Sttop function prevents accidental slip out at the fine adjustment of the clamping position. I have this clamp adapted to a Manfrotto Hydro-ball head and everything is rock solid !!! Me two fingers can be fixed ball head of Hydo. So one has leveled then in addition a panoramic axis of rotation by the Mengs adapter. An ingenious solution ...... I have never seen a better / more universal / stable ball head (in conjunction with this Mengs clamp) If there were 6 points, this product deserves it. Very strong buy recommendation.
