This dictionary is, simply put, superb. It covers a staggering range of words and compounds, it gives really thorough information about the grammar of most words listed (such as collocations, prepositions that go with verbs or adjetives and so on) so it is really what any learner who is beyond the beginner stage will need.
Also, a lot of examples are given, with the most usual idioms, sentences, etc.
Finally, the layout and the use of the blue colour are useful, and it seems to help somehow look for headwords more quickly.
I can't but recommend this dictionary to anyone learning German; dictionaries, particularly this large, are a must for people wishing to learn a language in a serious way, because not only do they give information about the translation of a particular word, but also how different phrases or sentences are translated, and how a word that goes in a particular sentence in English may not be translated with its usual translation in the quivalent sentence in German.
This dictionary, I must insist, fulfils all of these needs, and the price is OK for a dictionary of this kind and quality.
