Excerpt: I picked this up to use as a spare in my laptop bag... I'm carrying a 13" MacBook Pro at the moment but got this charger because it will also work with the 15" model. Nothing negative to say really except the new MagSafe connector does not seem as strong as the old one but that may be by design.
Excerpt: Had to buy a replacement for my original after a year and a half because the cord had turned yellow and started to crack near the connector. It was already out of warranty so Apple wouldn't replace it. Be careful when unplugging the magsafe connector, do not stress the cable.
Excerpt: I am always on the go, and this cords are won't help. I don't know if other individuals experience the same, but I am waiting for apple to design a more robust cord (@ this point and time, I lost hope).
