I will have to say that I was very skeptical about this program at first, but Pimsleur has definitely converted me! By unit 17 of phase 2, I was able to converse with a couple from Germany. Mind you, I do not have a
FULL vocabulary, but the couple said that my pronunciation was like that of a native speaker. Granted, I do spend more time than the program recommends per day and have had to repeat some units, but to be able to be understood by a non-English speaker after only roughly six months TOTAL (including this program and others) is impressive. Of these programs, I have used the Pimsleur program for about four of these months. I can speak better German than I can Spanish, of which I had four years of formal study.
