### ⭐⭐⭐⭐⭐ Impressively loud and quick to charge
*by A***M on May 2, 2025*

This is a loud amplifier that works almost too well. I got it for the kids to play since some of them like to play theater and dance. It can get a little bit too loud but if that's what you're needing this is perfect for it. The sound is clear and it's not heavy at all
