infringement or legal product?

the card comes, as announced, without any packaging. as it is not recognized at 100% by the camera that displays each access (read or record) a message saying that the data may not be usable (though, we get to read the data, phew!), we is entitled to ask the question of the origin. this is what seems to imply all the comments on the Internet. Sony, the manufacturer of the card and the camcorder, disclaims any responsibility therefore there is no original packaging :)
I recommend strongly for a few euros more to buy where the origin is "guaranteed"
