This book is OK. Not great, not horrible, but OK. There are a lot of projects in here (they say 50) however several of them are individual cars for a train set, which I would argue are pieces of a single project and not separate projects. The stuff looks nice in some cases but the aesthetics that two of the other notable authors come up with are a bit better, namely Jim Makowicki two books and Les Neufeld book on building toy trucks, which look a bit more like pieces of art.
My main complaint is that this book kind of misses the mark by making things too complex in several cases, or the drawings/templates are too small to be useful, or it makes the toys so simple you don't really need this book to help you. I doubt I'll make any projects from this book.
Like I said, try Makowicki or Neufeld, they have cooler projects, better step-by-step, and nicer drawings. Plus, the toys look way cooler.
