Query: Not worth the money at all

It's indeed very portable and super light in weight even when including the 1 AA batrery. But I totally agree with one of the above reviewers regarding the volume. "The sound is small like mosquito" as what we would say in the Chinese language. And the quality of the sound is very poor, too. With same amount of the money, you can buy other potable speakers with much better quality. I am browsing now to get a better one.
