Covered up with a microSD card slot, I finally again more space on your MP3 player but I would have bought one with a fixed built-in memory. Constantly changing the music Mp3 Player begins to spin and shows a Card Error. Then each time the memory card must be taken out and reinserted. With any luck, then does the music seem hören.Ausserdem not the MP3 player to be able to charge the battery for all. Although he indicates he would be quite loaded but if you remove it from the USB port is missing still a line and you have infected him again. Thirdly, the shutdown is missing do not use at. While he has a sleep mode but that is very cumbersome. With good reason not Grundig
