### ⭐⭐⭐⭐⭐ Small

Too small

### ⭐⭐⭐⭐⭐ Good
*by M***N on February 7, 2026*

Good Sound and price

### ⭐ BLUETOOTH SPEAKER BOMB!
*by J***N on June 1, 2024*

This was purchased and delivered all in one day and I thought I'd be able to use it immediately! NOT the case. All it did was give out piercing, loud frequency sounds. The radio mode didn't scan properly and the Bluetooth mode wasn't working properly as well. It operates as if it needs an antenna, but doesn't have one. The loud noises were too much to bear, so I am returning it for a full refund and that will be the last time I order this brand.
