Very nice MacBook Air, mine looked brand new with no damage or wear at all.  Worked perfectly from first second.  The only drawback is the battery life, its REALLY bad.  You can put it to sleep and within a few hours its already lost 25% or more.  Not sure how much it would cost to get new battery but, still this is a GREAT deal vs. the price of a brand new MacBook.  Overall would recommend it though, just know you'll probably be needing to stay near a power source.
