[Q]: This book should have been written more as a novel than a how to. This book goes into story like dimensions and there are others better written on the subject.
[A]: Negative


[Q]: I was very excited to buy this scanner and was pleased with its size and weight. However, if you have a Vista operating system, like I do, IT WILL NOT WORK! The company told me that they stopped selling this product over a year ago and there are no driver updates available for this product. If you have an older computer and an older operating system this product might work for you. But as for me it was a waste of money!
[A]: Negative


[Q]: In two of the episodes, the word "shut up" is used. My son is three years old and instantly picked up on it, repeated it, and told me it was a bad word, but that James and Duck (the trains) had said it. I would stay away from this one, especially if you have young, impressionable youngsters. I gave it one star, since the wooden dragon train came with it.
[A]:
Negative
