This is a pre-owned unit.  It is in great condition.   The only flaw is that the rubber coating on the wire towards the end is pilling a bit (see photo).  All you need is a tiny little bit of electrical tape to tape it shut. I am happy to do it for you if you prefer.  Just email me after you make the purchase. Note that this is an older model of Apple external drive.  But it will get the job done for you!
