Here is the best little desk device I've ever had I just don't use it much anymore as I'm out in the field most of the time now so it's time to clean the desk up but this has a spell check the dictionary a thesis the definition search it's a calculator and has testing quizzes on it so you can learn spellings of words all in this nice little box that can sit in a clean corner of your desk ohh I know phones have spell check now but nothing can give you more about the word and everything and anything you ever wanted to know then this neat little device for the price it's worth every penny of it thank you for looking and please ask any questions you might have
