In the end, I've found this book/tool to be useless in the sense that it's method is centered on learning with the Romaji alphabet (Japanese with Latin letters) for a *quick* learning experience. Then again, it doesn't help you if you're on site or trying to find your way in a Japanese context, with signposts, newspapers, books, etc. The idea to use small stickers to everyday objects/places etc. is laudable but at the end of the day, you'll only learn to speak Japanese, not write or read it, which is sad.

My Personal one; as CAT has one as well.
