Excerpt: 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 .
Pros: Durable and Reliable, Lightweight, Long Cord, Simple, The Magnetic Connecter
Excerpt: Having another adapter is really helpful. I go up and downstairs taking my Macbook Air and the battery only lasts so long. Having another adapter upstairs to plug into makes this a non-issue. No worries about getting a counterfit adapter when ordering from B&H (I wasn't so sure if I had ordered it from another .com, to be honest).
Pros: Adequate Power, Easy To Set Up, Reliable Performance
Summary: My children both have Macbook Airs. Between them, four chargers have frayed (same place every time) and stopped working in less than 18 months. They cost nearly 90 euro to replace every time, as we now live in the Netherlands (for a charging cable, that's extortionate), and thus, when my daughter goes to University this year, we are buying a non Apple laptop for her, solely because of this problem.
