"Talk about fast! I ordered an adapter on a Tuesday and had an email within the hour that the product had been shipped. I received the adapter by Thursday! The adapter for by MacBook works fine. It did not include the long plug-cord that comes with the original Apple product, that you would purchase for $79.95, but I was able to use my old one. At the price of $29.95, this was a great option and it only took a minute to put my old adapter in the mailer, attach the label and send it back. I would definitely order again!"
