[EX Q]: The book was new and in perfect condition. The price was well below that of many competitors. It was sent in a timely manner. I would gladly buy from this company again.
[EX A]: Positive

[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 loved looking at this book. It covered a lot of variety of types of chests and provided interesting historical and culture facts, as well as personal stories for specific chests. The pictures to text ratio is perfect. I wish there was a little more information on consrtuction--there was some useful information on types of construction for the wood itself, but I would have liked to see information on materials/woods used, latches, locks, handles, and strapping/corners. Still, I am very happy with my purchase.
