## Overview

The Braun 21B Series 3 Replacement Foil and Cassette Cartridge is engineered to restore your electric shaver’s original cutting power.

This cost-effective upgrade ensures a smooth, comfortable shave backed by over 23,000 positive reviews.

## Description

Within 18 months, Braun shavers cut an average of 6,000,000 hairs. That comes with some gradual wear to the cutting parts, which can lead to a less comfortable shave. That's why Braun recommends changing your shaver's foil & cutter block every 18 months to get your shaver back to its best. Take care of your shaver, and it'll take care of you.

Review: Excellent. - This fit my old razor exactly. It said on the back to use this part. I had the original blade on there. It didn't break and I never replaced it. This new one cuts amazingly nice. I hadn't realized how the old one was wearing out. My previous Panasonic razor would break every year or so (the metal screen). I would buy a new head. The Braun one never broke until now. It was tougher than heck. So nice to have a new head.
Review: Original Braun Part - Factory replacement works great. Much better than non factory even though cost a little more
