Query: Don't Buy It.

Don't buy this, unless you just have an overwhelming desire to waste 50 bucks. The sound on the thing is terrible. It has a button to click to slow the speed of the people talking, but when you click it, the sound is distorted. The sound is also sometimes distorted when a letter beginning with an 'r' is pronounced. And it's distorted a couple of other times as well. The sound on my computer is fine any other time so I know that it's in the software and not my computer. The product isn't really that good anyway, even if the sound were perfect. It's definitely not for a beginner. It lacks information that a beginner would need and it uses a boring method of building the vocabulary. So just don't buy this. It's a complete waste of money.
