I bought it on a HUGE special, so decent for that price. Not so sure for $14.99 like its currently listed. Closed unit seems fairly robust/kid friendly. Jack cord non detachable, tucks neatly away against unit. Expands about 1cm (“burger”), unit is less than 5cm in any direction when open. Disagree with “incredibly rich sound and thumping base”, sound quality reminds me of a transistor radio (like cheap ear buds). Full charge (separate USB cord) takes 4hrs, expected battery life only 1.5hrs. Will not impress serious sound fans.
