A couple of reviews I read of this book said that it would be useful for business travelers.  WRONG.  First, the vocabulary in this book contains very little that would be of use to travelers for either business or pleasure -- who typically don't need to know words for things like "dog," or "cat," kitchen appliances, bedroom furniture, or articles of clothing.  Second, the vocabulary in general is extremely basic.  Things like colors and numbers, while important, are hardly worth buying a book for.  Anyone who took as little as a year of French in school, even if that was 20 years ago, will likely be beyond the grade level offered here.  Finally, the design is cartoonish -- more like a child's coloring book than something that would appeal to most adults.  I admit that I found the stickers kind of cute and enjoyed pasting them around the house in anticipation of my upcoming trip to Paris, but their value in refreshing my college French -- let alone teaching me anything new that might be useful -- was extremely minimal.
