I bought this essay because I had indeed decided to use the epilator "Silk-epil 7 SkinSpa" - had however previously very wavered between this and the "Dual Epilator" (also Silk-epil 7). On Gutglück I thought, I'll buy separately this essay to try and if it fits .. and lo and behold: It fits and works flawlessly on my SkinSpa model! So I have the peeling Epilier- AND Rasierfunktion to choose from. Although I must admit that at the top is more than shaved depilated - but that one can imagine actually. This procedure is a little less painful, allows small hairs but quickly grow back. In retrospect, I'm glad to have bought the SkinSpa because I wanted an epilator precisely in order to epilation. On the attachment per se but there is nothing wrong, and price is okay, delivery anyway as always super fast at Amazon :)
