The MP3 Plyer works!. Disadvantage: No song selection - you have 30 times pressing the button >> to change to the album and then also in the order in which the music is played it. Lautsprecherquailtät is ok to good. Fahhradlicht is quite good - but focused heavily The bike mount is also good. A downside there is for the audio jack - which has lost contact (badly soldered) and I had to exchange the unit - but that was about Amazon wonderful (First came the new device, then i had 2 weeks in which the old to send in). Altogether 3 stars
