Query: It serves its purpose

This is a small dictionary that I have used extensively in my long struggle with the Czech language. It's small enough and cheap enough to be carried around easily and gives you a ton of words to learn whenever you get the chance. I use my huge Czech printed dictionaries for more intensive home study and take this book around wherever I go. I recommend it along with other works by this author. (By the way, other reviewers really need to loosen up, what do you really expect out of a small abridged dictionary that can be had in a used English language book store for kc50?)
