## Customer Reviews

### ⭐⭐⭐⭐⭐ Great
*by K***E on 25 November 2024*

Great! It works well, exactly as described

### ⭐⭐⭐ Acceptable
*by E***C on 23 July 2025*

I've been using it for 2 years, and it's good news that it's still working. The negative part is that the sound quality when speaking into the microphone can be improved, some people find it hard to understand me when I speak into the microphone.

### ⭐⭐⭐⭐ Compact
*by B***E on 19 October 2024*

A compact amp with strong reproduction qualities. As described by my sister. I have throat cancer, the amp didn't suit my situation, which is a bummer because it's a great little product.
