This product is better used as a bookmark only. As a dictionary the overall design and content leave a lot to be desired. As noted by other reviewers, the keyboard is too flexible where it needs to be rigid. The keys are not user friendly; very often duplicating a letter when it was touched but once. I, like others, have found the dictionary seriously flawed; not enough content, very frustrating considering the time it takes to input an entry. Further, I don't need a calculator or clock either. I suggest consideration of a different product, e.g., the SHARP E550.Get more detail about Zelco Electronic Bookmark Dictionary II.
