Love it. Compact. Lovely quality sound. Very quickly and easily pairs to my Asus Transformer and the aux socket connects it easily via a cable to my Sansa Clip MP3 player. Even the 8 year old technology expert in the family was impressed! It plays directly from the mains if required. Battery life and charging time seem fine, though I haven't timed them yet. Flashing light indicates low battery, then stops when fully charged.
