The product is good, but it has a major flaw for IPhone owners like me. I bought it for music and photos are the two causes of memory is always full of my iPhone 4S. As soon as I got home, I had the camera I immediately put my favorite music on memory. Through the implementation Sandisk I put into play a whole album, and at the end of the first song that the reader is stopped. Long story short, I realized that the songs will not play automatically at the end of every song you pick up the phone and manually move to the next. This is a problem with the iPhone on Android smartphone of my girlfriend walking. I turned to the Sandisk assistance and I confirmed that the music player on iPhone does not work automatically. Too bad I bought mainly for music. Sorry for the grammar I hope I have written properly because I'm Italian and I used an online translator.
