The product arrived with an impact on the side ... on Christmas day ... this is not TOP! My daughter, who was addressing this gift, however, did not want me to return the device too happy to use it! The blu-tooth connection only works on some devices (Galaxy Note 1 and 3), however, not possible to connect the Galaxy Tab 1 ... it's a shame! The connection by USB key is effective. The sound is clear and fills a large room for the happiness of large and smaller.
