Title: Paperback Very Poor Quality
Review: This "book" (you'll receive a bunch of copies sewed) has more complete instructions about how to do the exercises. The material inside the book is great (exercises seems to be very helpful for my brain); but I can't believe that I paid [...]USD for a bunch of copies; when in Mexico this book with a perfect paperback has a cost of 7 USD!! (I requested the perfect paperback here in Amazon).If you can get this book in the bookstore of your neighbourhood, please don't waste your money.
