[EX Q]: When I bought this book I was expecting more information. Most of it I've had heard before and could find very easily at the library. There are a few helpful tips, but overall, not worth paying for it! Unless you're someone who knows absolutely nothing about getting older, then maybe it's worthy - to save you some money. It only takes me 10 min to write my thoughts on every topic in the book.
[EX A]: Good Review

[EX Q]: If you are looking for a fast pace, action, and adventure story than this novel can fill your need. This book kept me awake for about 5-6 hours without putting any effort at all. It's just too good to put down. While reading it, I was able to learn how the author researched her subject matter. The details she included give an inside look into the time period of late 1800s England. Not many books that cover so much information do it in such interesting way.
[EX A]: Good Review

[EX Q]: Don't waste your money. This will not work for more than 10 minutes even if you have brand new batteries. Then it stops. Just like that. Do yourself a favor. Look elsewhere. The cost is worth saving some time. It doesn't seem to be possible that Amazon can sell this junk. So what kind of rating system? Would I put four or more? Zero stars seems much too high.
[EX A]:
Bad review
