I was made to buy this in high school, but I never used it. The batteries will be removed before shipping. The main unit's memory also includes a Chinese dictionary. Library > Main unit saved dictionaries I turned it on to check the functionality, and found that it has a lot of content, including brain training apps (crosswords, puzzles), today's dinner recipes, and travel guides with travel English in multiple languages, with voice output (reading speed adjustable). It seems like it would be fun to use! http://arch.casio.jp/exword/products/XD-A9800/
