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.
Bad review

If you love your dogs this is the perfect thing to give them! My husband likes to keep on eye it so he will be eating his breakfast in bed now! The only downside for me was that I wish they came with a way of securing them more securely. So far I'm still using it, but have had trouble keeping them together!
Good Review

My family has been using this product for many years. It works better than any other product. Have recommended to my friends.
