I would have liked a color display with cover display for mp3s. just for your little children that would be better. also the ON / OFF button on the side is my opinion not quite suitable for children. So insgesgesamt I consider the product design while for pretty but little thought out and rather irritating. Operation Wennig intuitive and cumbersome part. Shield in the form for example of a rubber seal on the SD card is missing. For this, the device is stable and is even supplied with a small AUX jack cable. Tonqulität is at low volume kids music and radio plays absolutely properly adjusted.
