This book is cute. My 2 year old son likes it. The names and descriptions of the machines are accurate, as well as the other info provided. The only drawback for me is that the operators of the machines are bears, not actual people. But this book is the only one I've seen so far that showcases an underwater backhoe, which is interesting to my son. All in all, it's a cute addition to a bookshelf, but I don't plan on keeping it past this immediate interest in all things "digger".
