not even worth returning for $7.99 but let me tell you it's a piece of crap. Not only is it not recognized by the computer, but the SD card (which was correctly inserted) cannot be terminated. The slot had a power grip and I tried tweezers and still nothing. Eventually the hammer did it, but I think the device is now more inoperable than it used to be. At least I think I salvaged an SD card that costs way more than this item.
