Braun shavers are very reliable. Nevertheless, the cutting parts the foil and cutting block wear down over time with repeated use. This is hardly surprising, as in 18 months you have already shaved an area the size of a football pitch! As a result, Braun recommends you replace the foil and cutting block every 18 months to ensure your shaver continues to perform at its best.This replacement part is suitable for Flex Integral 5550, 5525, 5520, 5316.
