sony memory stick

[ant1uk]

hi i brought a memory stick on ebay how do you know if they are real? i recieved it and it has the hologram on the packaging. it just feels rough when i insert it into my slot in my vaio. is there anyway of telling real or fake

Not really easy I guess, does it have Sony on it?
To be honest Lexar are cheaper so I use them

it looks the same as the ones in the shop only a couple of little things on the packaging, like some of the print, also it dont insert in the slot as smooth as my other ones do,

I would query it with the seller
