I find the material in the book meets my expectations and I would recommend the reading to others, however, I wouldn't recommend purchasing the "ebook" version. You should buy the book itself. The ebook version is one of the cheapest made I've seen and I've purchased a lot of ebooks. It simply is a flip page by page method ebook. There are no page numbers, so if you're using this book in a bible study group it's hard to use when others refer to the page their reading from. There's no menu or way of jumping directly to where you want other than flipping page by page. No way to highlight text, make notes or keep book marks.
