The dictionary content is pretty comprehensive and informative. I particularly appreciate the etymological notes on many terms - this is a lot less common of a feature in Japanese dictionaries than English dictionaries - and the markings of how each term is accented.
The definitions are often pretty stuffy and formal, which can make it a challenge to use as an intermediate Japanese learner. The 三省堂 国語辞典 feels equally comprehensive and the definitions equally informative, yet written in a much clearer style. But it lacks the etymology and accent information, so I use both.
The dictionary is supposed to have recordings of the terms’ pronunciations, but on my iPad I’ve never gotten them to actually work. For that I resort to using the corresponding app on my Android phone. :-/
