Great item and so much cheaper than buying the two parts separately, I have always found it better to replace both cutters and foil at the same time as this make the shaver perform as it did the day I purchased it. I also find the two parts replaced together seem to last a lot longer than when only one part it replaced.
i have used Braun electric razors for over 30 years and have always used their replacement foils and cutters which they make available for a good time after the razor itself is superseded. This purchase from shaver-spares.co.uk
was delivered very quickly and has been first class - as I knew it would be.
