The delivery was very quick. I have long and above all very thick hair (until the bra clasp). The product makes really wonderful beach waves in my hair, but I have a minus point: The product smells somehow extreme by a mixture of plastic and chemicals (I can smell now not exactly describe), and in conjunction with the heat, the smell always penetrating. Even my hair smell of it somehow strange to burnt plastic and I have the smell all day long in the nose. I do not use the device now first for a while, hoping that this strange smell in time from the product "flies / escapes" But the result with curly hair is really gorgeous :)
