Very outdated and not aesthetic flash graphics. The price does not match the quality. Visually done negligently. The first discs at least deal with several aspects of the topics, while the last discs have only a couple of phrases on the entire disc. Few words on the topic and one or two phrases are worked out. This is not enough. A complete system for the lesson is expected from such a number of disks, and there is only a joke. The guy is cheerful and energizing, but it looks like he was tired and gave up on his work.
