Been doing the Rocket German for about 3 months. So far, I've enjoyed it for the most part and am looking forward to getting into the second Level. My one complaint/suggestion is that I find the written lessons to be poorly set up. The focus looks like it is supposed to be on grammar in many lessons, yet they are taught with 20+ new vocabulary words in many of them. So instead of focusing on the new grammar rules, you get lost trying to figure out what all of the new vocabulary is. Would suggest using only words already known when first introducing a grammar lesson so that the focus is kept on the grammar and not diverted to the new words. I've come out of several of the written lessons with no more knowledge of the grammar rules then when I went in because 90% of the examples were with new vocabulary. Audio lessons are great though, and overall I still think there are many positives. Looking forward to the updated level one German whenever it is due out.
