## Overview

The TEEYSO Series 3 Replacement Head is engineered for Braun electric shavers (300s, 310s, 3010BT), featuring 3 flexible blades and a smart foil pattern that adapts to facial contours and hair growth directions. Designed for fast, close, and skin-friendly shaves, it’s recommended to replace the head every 18 months to sustain optimal performance and comfort.

## Description

Small investment, peak performance: Within 18 months your series 3 electric shaver will cut an average of 6,000,000 hairs. In accomplishing this substantial task, the cutting parts will gradually wear out and your shave may become less close and comfortable. That’s why we recommends changing your shaver’s foil and cutter block every 18 months to maintain your shaver’s maximum performance. For a perfect shave every day. How to replace your shave head: For older models which have a foil and a cutter block as two independent parts, you will need to change the parts in two steps: 1. First remove the foil, either by pressing the release button if you shaver has one, or by pulling the foil. 2. Next rotate the cutter block by 90 degrees and pull it off, holding it at the ends to avoid touching the blades. 3. To fit new parts, simply carry out the same procedure in reverse.
