Allows playback of a connected media data (eg USB) Writing for me could not be tested (My Moto G does not allow it). Attention all the time, I paid this a little more expensive than others, for his 3-year warranty, but I soon noticed that the product tends to remove too easily in the socket (the pins can be ?). In use it is really a problem as a mere nothing disconnects your devices. To see if others do better.
