The manual consists of two ring bound volumes (total 35mm thick) 645 pages of easily understandable instruction covering every aspect of about 16 iPad models including my iPad Pro 12.9-inch 4th generation. The many illustrations are in mono and my only adverse comment is that the print is rather small for my old eyes. The content is well laid out with no typos I have found...yet. I am truly amazed at the the vast number of 'things' the iPad can do, the manual index alone runs to 10 pages! This must be the ultimate iPad manual and I can recommend it for cost and rapid delivery.
