The sound quality is decent for a speaker of this price (46.99 to 06.26.2014). at the risk of repeating myself: perfect for viewing videos, a little low for music.
The build quality is good, and the molding solid aluminum has a very qualitative.
The choice of aluminum, however, has a problem: you can not carry this speaker in the same pocket as your tablet might scratch your screen or the shell.
Another detail that annoyed me: the enclosure comes in a jewel box nickname poor quality blue velvet result, the enclosure and cables are covered with a thin layer of blue dust. It cleans easily, but the first contact is unpleasant.
In conclusion: an original proposal on the market of bluetooth speaker, rather oriented video. The reasonable price can be traced back to 4 stars.
