Obviously, unlike at the time ...

I've now bought the second time a replacement shaving head, only to find that they are no longer equal. The sheet is obviously a little harder, so I suspect that the material is a little thicker ... and the blade / cutting also seem not to be as sharp as one would expect. Have the impression as if someone that I buy a new razor. Well ... Perhaps times as slow time.
However, had given a new two years ago to get (also brown), but I had brought back, because he shaved not nearly as good as my old baby 5443rd
BROWN ... if you will, that I buy a new razor, then you must first of all again produce something decent!
