This was an excellent purchase. It includes a CD which allows "hands-on" learning. My original purchase had a broken CD. I initially thought I would be ok without the CD. I did not contact the seller right away. When I did contact the seller they did not hesitate to send a new book with an unbroken CD. I am very pleased with my purchase AND the sellers quick response to my concern.
