Just my 2 cents.
I bought and read the book. It reads like a guide and how she handles some situations. NOT a how-to book. She explains how she organizes her properties and keeps track of her offers. When to use Sub2 vs Lease/Options and she gives some of her contracts clauses. I thought it was well structured and easy to read. Good for getting the novice familiar with Lease/Options and Subject 2 deals, when and how to use them depending on a very generic situation. Personally I liked it for what I paid. VERY VERY cheap education which could potentially get you started. It’s really up to the reader to make of it what he/she can and if there are any questions you could invest more into research or professional counsel.
Just never let a negative attitude sway you from learning. Most people fear what they don’t know then they “recommend” you don’t do it. Learn and find out for yourself.
