Extraordinary
For this price, its size and the fact that it's waterproof, this little Bluetooth speaker is simply incredible. It doesn't have a microphone or the ability to answer the phone, but from a sound point of view, it's very well balanced, even the bass is quite rich (again, taking into account the small size of the device). For use in the garden, in the shower or even just to replace the speakers on a tablet or smartphone and get near-perfect sound, I highly recommend it.
The only downside is that when laid flat, it vibrates and sounds on the surface it's resting on (when laid on edge, it's much less of a problem), but that's just a detail.
