I ordered 3 pieces, since my sister in the bathroom, kitchen and hobby room each has a USB radio. Dier USB Stick is perfect for this, as it is very small and does not protrude out half a meter! He does what he should do has also still a security program on it, you could so its data with a password in my or the use of my Schwesert indeed superfluous, since only is music on it, and every few months is just plugged in the pc updates draufzuladen but generally ne good thing.
