Within 18 months, Braun shavers cut an average of 6,000,000 hairs. That comes with some gradual wear to the cutting parts, which can lead to a less comfortable shave. That's why Braun recommends changing your shaver's foil & cutter block every 18 months to get your shaver back to its best. Take care of your shaver, and it'll take care of you.
