Works great - used very briefly as a backup drive (probably 1 to 2 full writes done to the drive, so it's got low hours/writes)
Includes AC adapter and a short usb cable.***Do not set this type of mybook drive on its shiny plastic side unless you have a rubber pad under it.Stand it up on its rubber feet normally.I've had another one of these units (not this one obviously) fall off my computer and was immediately rendered dead because of this.
