Query: Boring and hard to read..!!

Do not buy this book.. The information was very repetetive and worthless. The main advice in this book was to get a group of manufacturing, marketing, and patenting "experts" that would guide you through the whole process of product development ..!! The whole book keeps referring to these "experts" numerous times in almost all the chapters. I also didn't like the side quotes found on each page. They were distracting and offered no real useful information.
