PROBLEM: this book is one chapter per chapter. and it says each chapter.its only 10 pages long. don't buy! waste of money. i want my dollar back amazon! if you can't get any better than this! shame on you! no wonder the price is so low! it sucks so much.

SOLUTION: Bad review

PROBLEM: The book is quite interesting but a bit too descriptive and the pictures were somewhat blurry. Some of these paintings are so beautiful that I wished for more clarity in my mind to see them. All said, it was worth every penny. Would make an excellent gift and conversation piece.

SOLUTION: Good Review

PROBLEM: I received this battery from Amazon.com before it arrived here in Mexico. With the first recharge after 2 weeks of use, which gave me 5 hours using Firefox to check email, write letters, and browse the net. After my fourth charge, however, 3 days later, not even an hour on any program, but with a full screen view, all went downhill, fast. In 2 weeks, 10 times, at 90% power, I've gone thru three cycles charging it, then I'm done, so no new battery. This is a bad product.

SOLUTION:
Bad review
