This product works well. Remember to get the cord to transfer the data from your old hard drive to the new one. Wish I would have known how long the file transfer was gonna take. Took at least 3 hours. But our 120GB hard drive was FULL.
The new xbox 360 slim makes you sign in with your Windows Live ID email address so make sure you know that. :)
Our new xbox 360 slim is having problems with freezing, not sure if it's the hard drive or the unit. But yeah, they're not flawless.
