I've now finished all 1-30 units of Phase 1, in anticipation of a vacation to Italy, and am very impressed with the program. It's not your standard memorization / grammatical structure drills like we had in school. It teaches you conversationally, in a very organic way, that seems to assimilate and stick better. I think the conversational emphasis gives you a more natural accent too. Highly recommended.
This lesson is great, IF you've had the benefit of something else before. I've done all of the Pimsleur lessons, plus some others. This one is great for filling in the details like grammar, including the tenses that I hadn't learned before.
