I am currently learning German and this dictionary makes for a perfect tool. I have purchased it for my Kindle and associate all my German books to this dictionary. This allows me to read a German book, and by simply selected a word, I get the German to English translation (not to be confused with the English-German Collins Concise, which will translate from English to German). Note that it only goes one way (from German to English). I am very satisfied with it. Sure it doesn't recognize every word, but the vast majority. And it does recognize trennbare verben, which is a must. I have already recommended to many of my colleagues who are also learning German.
