To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I purchased this instructional book and DVD based on the ability to preview the book on Amazon. The book proved to be as expected, with lots of good basic information and illustrations, though the author's focus was on water mixable oils, and didn't cover traditional oil mediums in any detail (my current area of interest). It would have been helpful to have had this point more prominently advertised.
I was particularly eager to view the included DVD (a factor in my purchase of this book over others), but found the production quality lacking. Specifically, the volume levels for the two hosts was substantially different, and the demonstrators might have benefited from having a producer/director to do additional cuts to remove some of the woodenness any of us might experience in front of a camera.
I gave the product three stars instead of four because of the above two points, but I nevertheless found the information at an "absolute beginner" level to be helpful and a useful addition to my collection.
