## Review summary

Users largely praise Better Volume Booster for reliably boosting browser audio, even on very quiet laptops, and for being open-source. It’s deemed easy to use, with some noting it just works and outperforms alternatives, and it even offers mono/stereo controls. However, recurring caveats include compatibility issues on certain sites (notably streaming services and YouTube), occasional audio failure or DOA, and a confusing UX with no clear indication that the extension is active. DRM-related playback can be affected on some services.

### Pros

- Reliable volume boost that many users describe as 'just works' across most sites.
- Significantly enhances audio on quiet laptops.
- Open-source (FOSS) and well-regarded by users.
- Includes useful mono/stereo control for audio output.
- Better compatibility than other extensions and handles tricky media cases where others fail.

### Cons

- Can break video playback or DRM on some streaming sites (e.g., Crunchyroll, HBO Max, YouTube).
- Inconsistent performance; some users report audio not working or being DOA.
- Not always effective on YouTube (some reviews say it doesn't work there).
- User experience can be unclear with no obvious activation status or in-browser indication.
