Times have changed again after 16 months the shaving head and shaving foil of my Braun Complete series5, now for the third time since acquisition of the razor 7 years ago. So what really bothers me is the fact that there is no longer the original shearing blade in OptiFoil Quality at the exchange Combipacks. From feeling and shave ago I found the better. This shaving head system (51S) I have much more often go in different directions on the skin area to achieve a satisfactory shave! Wonder there is now only at the age of my shaver, or at least to this shaving foils of Combipacks ?! UPDATE after 6 weeks use: So the quality leaves much to be desired. After only 6 weeks of shaving head / -sheet is duller than the replaced after 16 months service life !!! As others have already written here, there seems to be method behind ?! Say, the previously used razor or the delivered spare parts is good for nothing, because the shaving three times as long and also lasts is still painful, probably a new razor must come from? !! The only way to ensure the corresponding paragraph of the new model series at Brown well?
