I was stopping by to see if there was chatter about the outdoor wrestling match just announced, but I happen to be very familiar with Rosetta Stone. I did about 100 hours of the Rosetta Stone "Totale" program in German, as I was going to live in Munich for work for about 3 months, and I wanted to make sure I could hold my own. My 100 hours got me about half way through Level 4 of the program.
It was a very good program, and people kept commenting how good my pronunciation was, that my accent was there, but that the actual pronunciation was spot on. Rosetta Stone uses native speakers for everything, and carefully selects people with "broadcast standard" accents (so like you would hear on national news networks, as opposed to "southern" or "new york" accent). My big test was always whether or not I could make it through a whole meal out without my waiter speaking English to me, and by the time I left Germany, I could do it without much trouble. I used nothing but RS, and was able to get around just fine and do everything I needed to. People were great to me because they understood I was trying to speak their language. I could not negotiate a contract, and lagged behind in meetings at work, but I was catching on to that as well. I think with 6 more months in Germany and continued time with Rosetta Stone., I'd have been very comfortable.
If you're just going to take a weekend trip somewhere, I'd probably just use an app and get the basic phrases, but if you want to be serious about it, Rosetta Stone is a very good option, particularly for an adult learner. I took 4 years of spanish in High School and spent a summer in guatemala. My level of proficiency on the street after 4 years of high school was about the same as my proficiency level in German after 100 hours of Rosetta Stone. My pronunciation was actually better with Rosetta Stone though, as you only hear it from native speakers, and you basically mimic the way they say it.
Tell me more was another product out there, but didn't use the immersion method Rosetta Stone does. Rosetta Stone actually bought tell me more, and I don't know of another program that is as effective as a self study immersion program.
Hope that's of value to you.
