I also bought this dictionary, I have to say I was not really convinced of its usefulness in the beginning ... now I find it handy to have small size in my bag when I'm in the TER and I read my HP 7. This finally allows me to understand the words that had escaped me in earlier books and I did not have the courage to look in my "big dicos." So, even if I do not try every time, because I want to move forward in the story (unless truly the meaning of the sentence escapes me), I use still easier and tell myself that when I reread all I can mug up the dictionary before ...
