question:
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!
answer:
Negative


question:
Koontz can write. But he sucks as a story teller. Books are supposed to have a COMPLETE story in them, no? Well this one has no ending. No end at all. These 2 detectives are clued in to the fact that Dr Frankenstein exists, and is creating his "perfect race" to some day kill off all humans. That's it. You meet the original, now educated and "at one with the universe" Frankenstein's monster, you meet the main characters, and they have some conflict. That's the whole "story" in this book, which it really isn't because the basic elements of a story are a beginning, middle, and end.
answer:
Negative


question:
