[EX Q]: Although this is a wonderful working power adapter, I don't believe it is the Macally Adapter that was advertised. I am however happy with it and would shop with this vendor again.Thank you.
[EX A]: Positive

[EX Q]: Like all of her Scarpetta mystery novels, Patricia Cornwell has proven again that she must have been one dynamite of a Coroner when she was practicing. She has a wealth of information in her books and it is so interesting to follow as she progresses to solving the mystery. I've never enjoyed reading as much as when I pick up a Cornwell novel.
[EX A]: Positive
