We wanted to replace our failing dictionary/thesaurus with a newer product. After looking on Amazon at various reviews, we settled on this one.
We felt that the encyclopaedia would be an added bonus albeit that we only really use it to help with crosswords when we're stuck. It's on this latter point that the ER6700 falls down. Whereas, with our previous electronic dictionary/thesaurus we came across anomalies when a dictionary word didn't appear in the thesaurus and/or when using the crossword aid to find words where we only knew some of the letters, again, dictionary words didn't appear in the 'solutions'. However, the EER6700 does much worse and many is the time when we're stuck for a word, the crossword helper comes up blank.
Very disappointing that the manufacturers of these machines can't seem to find a solution to the problem of linking the dictionary to the thesaurus or to the crossword helper.
