Query: Dictionary? What dictionary?

If you are looking for a robust Ei/Wa:Wa/Ei dictionary, stay away from this item. It's dictionary is atrocious. It is missing the most fundemental words. For someone with no kanji skills, this might be a good tool, but if you want a resource for finding that word you just don't know, you won't find it here. Returned for refund. Very expensive mistake.
