Query: Very good tool that helps create great progressions quickly

The chord wheel has helped me greatly in creating more interesting progressions very quickly. It has 12 pages of information that tells how to use the wheel on the front of the book. This information alone may not be enough to get the most use out of this tool, but it does help. I would recommend this in conjunction with a good music theory book. Edly's Music Theory for Practical People would be a good choice to pair this tool with. Regardless of how much theory knowledge you have, it is well worth the price and is a very good tool. I have told many friends about it and almost all of them have purchased one. They have also found it very useful!
