My first impression upon receiving it is that this software is significantly overpackaged. A single disc in a paper sleeve packed inside a 2 inch wide cardboard box is unnecessary.
The product itself, however, is pretty good. This is the first time I've tried using software of this type and, having been rather sceptical about the concept, I've been pleasantly surprised. The software was simple, straightforward and quick to install and was ready to use within minutes of popping the disc in to my Mac.
The lesson plan seems (to a beginner like me) to be pretty comprehensive. There are over 300 individual lessons, subdivided into a series of chapters and there's a good deal to work through. I'm still in the early stages, as I only received the software a few days ago, but so far it seems clear and easy to use and I'm quite optimistic about the progress I'm making.
Trial versions can be downloaded from the manufacturer's website - so you can try before you buy.
