Very low price and it works

For a very low price allows for still in the camera bag an SDHC adapter. Once the card is inserted the back cover can be closed and used as a USB key. The front and rear covers are used to protect the connectors from dust. No recognition problem for the moment on my Samsung Galaxy 2 via OTG cable (used to view photos on the AMOLED screen via RawDroid example). A small LED indicator informs if the player is actually supplied or not. Obviously, avoid lugging plastic product with your keys in a pocket but tidy in the camera bag problem. Also avoid hot unplug without eject the player via the System icon.
