## Customer Reviews

### ⭐⭐⭐⭐⭐ Klein und praktisch
*by H***S on 28 December 2025*

Eine praktische Lösung, wenn man vor lauterer Kulisse präsentieren muss.

### ⭐⭐⭐⭐⭐ Great device helped me during a field trip
*by T***. on 2 July 2026*

Great device saved my voice

### ⭐⭐⭐⭐⭐ Substitute gym teacher approved :)
*by D***N on 2 April 2025*

I use to be a Substitute gym teacher and this device is indeed ... loud. Works wonderfully inside the gym and classrooms. This device does win 5 stars BUT! My only complaint (or recommendation) is how the ON and OFF works on this device. It should be a button, not the way that it is. If they can fix that one day, this would be 10 out of 10. Still 5 stars overall.
