content: I previously owned the 1GB version of this card and was very pleased with that. This is a great improvement as it doubles the space! I've had no problems with it used as a USB key or SD card.The ONLY issue I have had with these cards is they DO NOT work in the Nintendo Wii. They WILL get stuck inside the Wii slot and with-out carefull pliers work you won't get it out. The card electrically works in the Wii you just can't get it back out. Same with the 1GB version. This is more a design problem with the Wii (which I still love) than with the SanDisk card. So get the card, just don't stick it in your Wii.
