for that price there (under 30), this is a perfectly acceptable pregnant. small enough to be carried away, deep enough to have low correct and powerful enough to share the sounds you love ...
I use it on my bike (I tinkered a system with a stretcher on my handlebars), or when I prepare to eat, or when I want to discover sounds to others ...
I also use it very often to improve the sound of my laptop when you watch movies on it (with the jack-jack wire supplied even need the bluetooth)
it has a very good battery life for my needs.
and THE reason why I redeem several times (except its affordability) is that it has a line-out plug (in addition to the line-in input)!
What makes it a bluetooth adapter - which cost them only almost the price of this speaker - to put his music in anyone (eg my parents who have only a hi-fi) by Through this forum will serve as a "bridge" between my wireless phone and good chain (with a more powerful amplifier and speakers) to finally listen to good sound at home! ; O)
(Just a jack-RCA cable (or jack-jack, depending on the hardware) to connect the two, and voila ...)
