## Customer Reviews

### ⭐⭐⭐⭐⭐ Ideal to have as a spare clarinet mouthpiece.
*by R***E on 27 September 2023*

Arrived promptly. Fitted well without any problems. Good sound.

### ⭐⭐⭐⭐⭐ Very good
*by J***E on 28 December 2025*

Arrived quickly, very good.

### ⭐⭐⭐⭐⭐ This worked fine for me
*by M***N on 9 April 2017*

This worked fine for me, though I found that I needed to use a softer reed to get results I was really happy with. It was a bit of a tight fit on the barrel of the clarinet, but some careful adjustment of the cork with very fine sandpaper solved that. Not sure if this is recommended treatment but it solved the problem. I'm only a beginner, but I'd recommend this one. I can now go from A to B Clarion without squeaking. Great .
