Have always used a Braun shaver, and regard my 7 series the best yet. The cutter foil lasts me about 4 months as my beard isn't that thick. I always use the shavers.co website as they offer quick delivery on what is a genuine Braun spare ( have had doubts about the quality of a purchase elsewhere)..
Arrived promptly & product as advertised.
Required item easy to find, prompt service, just what was needed.
