The Gadgeteer have published a review of the HOMADE LEGO MP3 Player. ‘Using the player is very easy. Holding down the Play/Pause button for a few seconds will power it on. From there, you can use the Play / Pause button to start playback. There are also buttons for next and previous tracks, as well as volume control. This is a very simple player. There isn't an LCD display to show you what song you are playing. It plays songs in order of storage and the sound quality isn't any better or worse than other inexpensive audio players that I've tested.’
