I purchased this card based on the price.  After I ordered it I finally started reading some of the reviews and started getting worried about whether the card was going to work.  Seems that a lot of people have been having problems getting the phone to recognize the card and then, if needed, formatting the card.When the card arrived I put it in my phone and it immediately was recognized by my android system (JB 4.1.1).  I had already copied all the music, pics and video off my older, slower and smaller card onto my computer so all I had to do was plug the phone into the computer, open the card and copy everything into it.  Everything went in with no problem.  I then unplugged it from the computer and tested my videos and music on the phone and everything worked like a charm.Bottom line, I did not have to format the card, I just plugged it into the phone, it was immediately recognized and worked like a charm.I would highly recommend this card based on the price and the product that you are receiving.
