Revamp the performance of your Braun shaver to its optimum with this Braun 73S Shaver Head Replacement Cassette in silver. Featuring quality craftsmanship, it is 100% made in Germany and compatible with Series 7 shavers. This shaver head’s 360 adaptation makes shaving easy and smooth even in tricky areas. Ideal for efficient shaving, it features four synchronized elements that capture in one stroke what others do in two (proven on a three-day beard IPI Research Institute, February 2015). Simple to use, you can easily attach your new shaver head - just by clicking it on. Care and use: It is recommended to change the shaver's foil and cutter block every 18 months to get the shaver back to its best.
