[EX Q]: I was excited to get this book, it looked like such an awesome deal. But as soon as I put my order in they canceled it and sent me instead. It took them three days after they told me we wouldn't be getting the book. Terrible experience. They also just cancelled the first one over night. Amazon needs better tracking systems.
[EX A]: Bad review

[EX Q]: I had been planning a trip to the Galapagos Islands, and this guide was required reading by the tour group guide. The guide is thorough, providing information of interest and useful for all travelers traveling among islands, but the format of this book severely detracts from any pleasure of seeing them. There's an interactive CD-ROM provided which allows you to see photos that were previously in the book, but not the whole trip. Additionally, there are many grammatical or spelling errors.
[EX A]: Bad review

[EX Q]: They work as advertised...at first. By week 2 or 3, not so much. Good concept but poor design. I'll switch back when these are finally garbage. My wife likes them though.
[EX A]:
Good Review
