Like everyone else is saying, this is absolute garbage and the company is trying to scam you by posting bogus 5-star reviews on Amazon. All products by Transparent Language are basically a 10-page piece of text spoken aloud by a native speaker. To lay the foundations of your language learning they use short, useless help files (a one-page list of the letters of the alphabet and a very sparse introduction to the different parts of speech) and nothing else. What they're selling individually for $40 and $50 was originally all bundled together for $10 on the "101 Languages of the World" CD, but as you can imagine they're making quite the killing doing things this way.
