Bought this to use in my Samsung SIII as it was supposed to be a fast card. Worked fine until it totally died after less than a year of very little us due to the design of the SIII. Phone popped up a message that the SD card had been removed (it hadn't). Nothing I did to the phone brought the card back up. Removed it and tried it in my laptop (Win7) and other computer (XP Pro) and it is totally dead, neither will even recognize its in the drive. Working with Sandisk to get a replacement, they want all kinds of fairly useless information, will see if I get an RMA number and replacement card.This is the first memory card I have ever had fail.As an update, warranty service from Sandisk has proven to be non-existent. They first asked to have over 16 questions answered, then mysteriously lost all the answers I sent back, three times.
