## Overview

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

## 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: Braun replacement shaver head - Package arrived in good condition and on time. The product was as described and worked perfectly.

### ⭐⭐⭐⭐⭐ Braun replacement shaver head

### ⭐⭐⭐⭐ 5 star performance, 4 star pricing
*by S***S on September 17, 2024*

Amazing! This worked better than the original head on the razor! I would give 5 stars, except I completely dislike how razor manufacturers abandoned less expensive replacement foils and ability to access the blades to clean...for replacing the whole head more frequently at a higher cost. Anything to separate us from more $ unnecessarily. Great product, poor after-purchase replacement support.
