    I really liked the way the author wrote this book. It was easy to understand by providing step by step instructions and pictures as well. Great book.
  • Lots of illustrations

    I have purchased some of the more expensive “Visual” books before but I think this book has way better images that are large and easy to follow. It has easy to follow steps to get everything setup. Plus, it additionally has videos as well. This was a good purchase and I do recommend it.
  • Really good book with lots of pictures to follow

    I was pleasantly surprised with how many pictures and videos are in this book. This really makes it so much easier to understand. Additionally, the pictures that are in the book are clear and large, which makes it really easy to see. Setting up email and messaging was a no brainer as there were step by step instructions, again with pictures. This is good solid book.
