To my Braun Silk Epil to expand and also to take advantage of the great exfoliating function, I bought this coupling. In the operation, I have nothing to complain about, adjust the scrub brushes and do what they should. But after the first fall of my Silke Pils including plugged clutch jumped herraus one of the "Aufsatztielchen" the clutch unnd could only be repaired with just barely (and know-how of my father). I find that very disappointing and would shcon dissuade me from buying again!
