It works great on my kindle touch as a default dictionary for French documents. That documents are encoded in French is important because many documents are encoded as English documents. You can use calibre (free open source software) to change your document's language to French if needed.
About this dictionary, it has nearly all words I look for. In the rare circumstance you find a word it doesn't have, you can fire wifi and use bing translation o wikipedia.
The most important feature for me, because I am learning French, is that if you open the full-definition there are the phonetics :D
It is well worth the money.
