[EX Q]: The adapter worked fine for my power book g4 for a few months and then it broke. Nothing physically happened to the adapter for it to break, but suddenly it just wouldn't charge any more. What's interesting is that the blue light on the brick goes on when plugged in to a power source, but if I plug the cable that attaches the computer to the brick in, the light goes out and it doesn't charge.
[EX A]: Negative

[EX Q]: I am sorry to all of you who like this book but I would never wish a single soul to read this. This book has the plot: a girl goes to a farm, falls in love and everything goes wrong. The book just goes on and on. The only reason I read it was because my mother asked me to. This book could have been written in 50 pages but no. It goes on for 300 some odd pages. I would have rather read the dictionary. The only reason I give this book 2 stars is because there was maybe four parts that consisted of 2 pages that were mildly interesting. Take my word for it. This book should be skipped.
[EX A]: Negative

[EX Q]: great idea the issue is some people (me) dont have the "flap" that these fit into on my ear, the top piece needs to be at least 5mm longer to fit without falling out. the teacup ear bud works better.and since i opened it i cant return it way to go amazonif your ears dont have deep folds do not buy these.
