When I purchased my laptop I was under the thinking that by old version it was the best last one released pr maybe the one before that. I ended up with a great little 2009 macbook air and a terribly mangled charging cord. If I had known that at time I would have not purchased it. I also feel like for the condition and age I should have been as much as I paid. I had completed sending it back for a refund, but due to the fact that I am a student and its next semester which is next to impossible. Overall if I dont think about the fact that its not what I thought it was, paid to much for it, I had to purchase a new charger.
