Braun Shaver Replacement Part 51B, Compatible with WaterFlex Shavers, Black

Within 18 months, your Braun electric shaver will cut an average of 6,000,000 hairs. In accomplishing this substantial task, the cutting parts will gradually wear out and your shave may become less close and comfortable. That's why Braun recommends changing your shaver?s replacement foil and cutter block every 18 months to maintain your shaver?s performance. For an right shave every day.
