You cannot buy genuine 16GB USB flash drives for this price
Seems that ganniniang1 is a new gremlin ID set up by a familiar fraud gang to sell fake flash drives on ebay. You cannot buy a genuine 16GB flash drive for this price – all you will get is a fake which will cause your files to be lost or corrupted.
As usual we strongly advise ebayers to test all flash memory with the free program h2testw.
Report in to SOSFakeFlash if your testing confirms you have a false capacity device.
