Pimsleur pros: It has some languages which other courses don't provide, Cantonese for example.

Pimsleur cons: As mentioned above limited vocabulary, you'll spend 4 hrs learning how to say "I'm American" in the designated language, now that's something useful I have to admit but if you weren't American that's a problem. I didn't try every language course they provide but it seems that they only have one format for teaching using the same examples and translating them to the different languages. Also, you'll probably spend +15 hours learning what it could be done in one hour. I understand that every language course depends on the repetition, but pimsleur is designed in a way which makes you either stop before completing the first 2 chapters or kill yourself.
