The average Braun shaver cuts 6 million hairs every 18 months, meaning the head gradually wears out and your shave can become less close and comfortable. 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 will take care of you.
