My granddaughter uses the Macbook Air for college, but, recently the cat decided to chew on the wire to the power adapter. It still worked fine but with wire exposed it posed a safety concern. I know there has been a lot of problems with this adapter reported on user boards, but, this one has lasted for nearly 5 years with no trouble (other than the cat). I considered replacing the wire and still may when I get time and inclination. For now buying a new one was the best solution. This supplier has the best prices, no sales tax and a good track record.
