Unfortunately I purchased this item before the previous reviews were submitted, and I agree it's a complete waste of time...if only I knew before.
The instructions supplied stated I simply had to plug the transfer kit into my Xbox. However this did not work because the kit was a USB instead of a data cable and my Xbox would not accept it.
I had a backup option of downloading files from a website, but the disc I was provided with contained a Trogan Virus, so I wasn't prepared to take any chances.
I have since purchased the offical product which was hassle free, as soon as the data cable was connected my Xbox acknowledged it and my data was transferred within minutes.
I should have known the price was too good to be true, beware and don't make the same mistake, it's just not worth it.
