Every sd and micro sd we have ever bought from china has turned out to be fake (5 of them). This will cause you to loose anything that is stored on it. What they do is take a 1gb (example) and relabel it 4gb and fake format it to show 4gb capacity then when you are storing to it and it reaches the real 1gb capacity it will go corrupt and you loose all your pictures..
Don't waste your time on this and just buy it local to avoid the whole mess.
