I ordered 2 copies.
Great info, but IMO very very poorly written. I still recommend getting/reading it. But if they put out a 2d edition, I hope they get an editor. Or better yet, completely rewrite.
Side note: People were claiming the book is 5x5. It’s not. It’s 6x6 - measured in inches. Maybe it’s 5x5 using some other unit of measure.
