I was in two minds about buying this book after reading the previous reviews. However, I am very happy with the purchase.
The book is great for students new to the study of rocks in thin section. It covers all of the most important rock-forming minerals and then introduces the rocks that they are most commonly found in. There are also sections covering most of the most common and important textures. The accompanying text is simple and easy to understand and does not become bogged down with elaborate language or over-complication.
All in all, a good low-cost option for 1st and 2nd year students who take fright at the price of Mackenzie's Atlases.
