This is just like the one I have used at work, so I had the trust going into this decision.  And I wasn't let down.  The box was a bit bruised, but it runs like a champ.  They had opened the device to replace the hard drive, but didn't bother to blow out the dust.  On a refurb, you expect to see some effort made to clean it up, inside and out.  But everything works great.  And what a phenomenal price.  I would buy this all over again.
