We buy these fools on repeat annually for my husband’s Braun razor. It’s easy to replace. New foils extend the life of these expensive razors. And give a clean cut. We hope Amazon continues to carry these. Highly recommend.broad_st_bully_16

I had ordered a cheaper replacement foil and blades that saved me a few dollars.DON'T.... The extra money spent was well worth it. The smoother heads snap on and off much easier and don't tug my skin.The blades cut much closer, much faster.Do yourself a favor. Don't skimp or hesitate on buying these original replacements. It's your face.... it will thank you later.stanley stone
