Effective and affordable small speaker.

I use it mainly for watching movies on computer and work pieces of classical guitar recorded on a portable recorder in live (I record my teacher). Perfect for movies. Saturates sometimes on low for restitution of guitar recording.
Power good for a room of 30m2, very good battery life of 8 to 10 hours, recharges in less than 2 hours, carrying over his small canvas bag. I think a good price / quality for a booster pregnant.
The cable attached to the enclosure is a little short, but provides additional cable (USB connection for charging the speaker + earphone jack) compensates the issue. Beware enclosure closed system because the plastic lugs are a bit fragile: Handle with care.
