I was looking for a boom box, but did not want hundreds of euros for a JVC or similar issue and pushed through Amazon on this "little guy". After initial skepticism regarding gymnasium suitability and volume but I am now pleasantly surprised by the device - a very good price / performance ratio and compact dimensions. For training groups and the picnic on the green meadow ideal. MP3's are played cleanly and USB and SD slot fulfill most desires. Sadly lacking separate controls for bass and treble, but a "Bass button" brings something fuller sound. Therefore: 4 of 5 stars.
