Excellent. The only issue is that is works so well most of the time that you sometimes get lazy and use it before you've even attempted to read the sentence.
Functionally it sometimes translates a part of a phrase or conjugation, instead of the whole thing. Though I imagine that's hard to avoid with a complex language like Japanese.
