Bests & Worsts Reviews from Amazon

This is a review of the format/packaging of this product, it is not in fact 4 separate ebooks, but is in fact one large ebook that has no table of contents, no index, chapter. It has no feature to even jump ahead to a specific book at all. It defies the purpose an electronic document. This is poorly put together and should not be purchased at all. Buy the books separatly.
