I bought this MWD-460 and is the poorest quailty I have ever seen.
Opening the case is the first major challenge. Then trying to set the time and date is a nightmare, I was never able to do it. The screen is lousy and poorly lighted. To use this as a spell checker you need to know how to spell pretty good to start with or you can forget about finding the correct word. DON'T WASTE YOUR MONEY ON THIS ONE.

I have had my Franklin Spanish/English Dictionary for several years and use it often, if it was lost I would buy another of the same... As it is, I'm back for one, minus the Spanish, as a birthday gift...

This is a great product, especially at such a low price.
The best feature for me was the list of SAT words and flashcards. It was more efficient than making index cards or studying definitions from a regualar dictionary.
The time it takes to define a word is fairly quick as well.
Some definitions include funny etymologies toward the end that really help the word stick.
There are a few drawbacks to the product. For instance, the screen doesn't light up, the word list can't hold more than 40 words, and the buttons sometimes tend to be unresponsive.
Still, for about $30, you get more than you'd expect. At least if you're in high school. If you're an adult, then a dictionary with a larger word capacity would be a better buy.
I definitely recommend it! :)

I bought this for my daughter to help with spelling. It was useless for that purpose. For example, typing in the word "becus" came up with "basis" and "bassos" but not "because."

I leave it on my nightstand so I can look up words without pulling out the giant dictionary everytime. So useful for a quick definition. Exactly what I wanted.
