My wife bought this same model dictionary about 10 years ago. We have both found it very useful and reliable. We purchased this one for our grandson based on our good experience with the previous one...which still works just fine. He is really thrilled with it and has been showing me some of the capabilities like the "learn" color key feature to list new words learned. The "say" feature is very helpful to him to get the correct pronunciation when he encounters a new word. I find it much quicker for myself that getting the Webster out of the bookcase or looking it up on Google.
