bought it on ebay from eastcoast-exchange. it was supposed to be a 64gb micro sd card. it was in reality a 4 gb hacked card.the package has the word format misspelled under" mp3 music fomat." has 64 gb in blue on front of card.the seller gave a full refund and told me to keep the card.. that it must be defective.but expected a positive feedback from me..i reported it to ebay.. but I don't think it will go anyplace.
