Battery is awesome so far. - Theres a small piece that holds the two wires together, and can slide up and down. Easy to assemble and use. Overall Im happy with my purchase and I would recommend it to anyone who cant go a minute without listening to their music like me. This speaker worked fine for a handful of floating excursions, but after the last one a few weeks ago, it does not accept a charge. I am shocked and disappointed beyond words! I feel like a decent pair of shoes adds a level of psyche as you put them on and even as far as psyche from the feedback each foot strike. Great purchase, at a great price. The leg attachment is great, don?t have any issues there. These also appeared to have been worn already or tried on by A LOT of people.
