Query: By Far the BEST Russian-American English Dictionary

I bought this dictionary along with another publisher's pocket one, and my Russian friend for whom I bought it and subsequently shipped it to says he loves this dictionary and actually prefers to take it with him as his English-Russian translation dictionary of choice - he calls it "your big translator" when referring to it when communicating with me. I flipped through it before shipping it to him and found the vocabulary quite comprehensive, as compared to the tattered one he had when I visited him and for which this one was intended to replace, as it clearly has. He loves the U.S. so I thought this translation dictionary most appropriate for improving his English vocabulary. I'm so happy Amazon carries this item, that I found it, and was able to obtain it for my friend. Excellent find!
