Most of the eBay ones are FAKE. ALL of them from dealextreme.com are FAKES
They are packaged exactly the same, look the same and even work fine in some cases.
So who cares if it is fake?
You will when your data gets corrupted or the stick just plain dies.
Here is how you can tell for sure if you have a PSP and are testing a Memory Stick Pro Duo
-Navigate to your Memory stick
-Press X on 'Information'
If next to "MagicGate" it says "Supported". memory stick is Genuine
If next to "MagicGate" it says "Unknown". memory stick if FAKE.
