I liked the device really liked at the beginning! It was pretty small, light and very loud with good sound quality! But every time I have withdrawn it from power, it went out immediately. The battery was in it and the lamp for charging was, but there has probably still not charged ... Had it at the normal outlet and also on my laptop for a few hours, yet it did not go without cable. I was very sad and then returned the device. The unit was to return not exactly straightforward, because it is needed the bill that was sent to me only when I repeatedly asked, although still on the delivery note, that I would get the bill automatically via email. An additional form must also fill out and include with device. Now I've been waiting for several weeks later to get my money back ....
