The printing is poor. The applications are unclear and, once dechipered, simplistic and unlikely. The small amount of actual writing is poor in execution and lacking in actual information. Three pages (a significant amount in a book this small) are wasted on a meaningless introduction and an explanation of what karate is which is pointless in a book which no beginner has a use for. The incredibly cursory section on the rhythm of the kata is less than useful, in fact it's barely better than indecipherable even if you already know the kata. There are technical mistakes in the pictures and the foot placement diagrams, admittedly not major ones as far as I've seen. The "Important Points" sections are laughable: "In it, of course, are techniques are of fast and slow tempo,". A quarter of a page for each kata's important points and the best they can say is that the kata is like every other kata. It is too damn expensive for a poorly printed, badly laid out paperback only 143 pages long.
But, despite all this, it's a must have if you are buying any karate kata books at all (well, after Best Karate: "Heian/Tekki" and "25 Shotokan Kata by Sugiyama Shojiro" if you can find the thing). Just remember that these books are the standard because they are the only books of their type and they are just good enough to be not completely pointless.
