I tested on arrival. My computer took him for a threat and refused to open it. So he had to struggle to put her new music, once that is done I exit test my new MP3. When I wanted to adjust the sound level (too hard) with the + and - I changed songs by pressing the swimmer he would pause a moment and restart and the last key was passed to the next music. So I dropped out of my shirt (where he was holding the crowbar) and there is the clip that was dismantled ejecting a piece from one side and out the other. I was left with the device in hand. Being out I did not find the 2 pieces ejected. I return the unit.
