Had a chance to come across some negative remarks upon this book. This makes me write some different opinions.
Ofcource there may be a lot of players who are disappointed with this book because of various reasons. A true chess enthusiast with a vision of what is chess composition and how is it beneficial to the chess world must be grateful to the work done by the editor Mr. Martin Greif. (though the original credit goes to the maestro's who have composed those wonderful creations)
Nowadays players turn to lite chess by playing in fast formats like rapid, blits, lightning etc. thus the whole game ending in minutes or even seconds !! Then how can you expect somebody to go for some time consuming problems
This book is not for all chess players. There are some minor and negligible issues with this book. Anyhow I give this book. 98% marks
