I use for many years the Braun Syncro 7680. I renewed every 18 months shaving head and shaving foil and was always amazed that my razor again like a new shaved. But now I realized that the quality of the shaving head is changed. The razor appear coarse and clumsy than before. The shaving is less thoroughly than in my old used shaving head after the first attempt and the skin does partially hurt. One might think that you have bought a counterfeit. If it is indeed a question here of an original, this will certainly lead to a loss of image for Brown.
