Simply insufficient without the "Teach Yourself Russian Grammar" guide. When I tried to learn anything from this book it didn't stick. Over-reliant on thematic dialogues.
Teach Yourself is the best guide out there for learning another language. There may be better guides, but you can bet they're more expensive. There are also severely over-rated guides like Pimsluer, who will as promised teach you to converse in another language quick and easy, so long as your idea of learning a language means using eight cds to learn four paragraphs worth of dialogue.
The Russian guide is severely lacking in grammar guides, audio exercises, but is still quite helpful. You will have to learn Cyrillic to proceed with it though.
I stopped because I had other business to attend to rather than learn Russian. I made it 5 chapters into the book and it was definitely worth the $20 I paid for it. The lessons were just the right size with enough redundancy that by the end of the chapter I felt comfortable with the material covered. Grammar was covered as necessary.
I pick it up when I have time and have learned 5-10 expressions and beginning to really recognize the alphabet and sounds each letter or sign makes. : )
