For the beginner, praying the Divine Office is tough. As a result, many (like myself) might not want to go out and spend a large amount of money on the four larger official books that make up the Office used by priests and religious until certain that this kind of prayer is of benefit.
For the novice, then, this work is excellent.
One caution, however: this book is difficult to navigate at first. It does take time to set the ribbons where they need to be, but an easy read through the introductory sections can alleviate some of the burden. I'd also recommend that you run over to the Liturgy of the Hours Apostolate website and view their free texts to make sure that you are indeed saying the Office correctly, since they have everything laid out in full on each individual prayer.
Overall, a wonderful selection for anyone looking to pray the major hours.
