How to recognise fake memory cards and controllers?

[spooky]

You will probably find that it is almost impossible for the likes of you and i to spot the difference between a genuine Sony product and a well made fake as even the serial and model numbers would match the same system used by Sony! A badly made copy should to some degree show some flaus in its construction like badly printed or smudged logos or poor quality materials used.

This is probably best left to the experts!
