This work is excellent as an advanced introduction for the serious student of Paul. Sanders indicates that the book was written with undergraduates in mind, and it is appropriately accessible. On the other hand, it is quite comprehensive. I've read thousands of pages on Paul, and Sanders has plenty of new things to say, as well as refreshing perspectives on familiar issues. He is the opposite of many writers, who trumpet their exciting proposals only to deliver arguments that don't quite carry the weight. Sanders adduces example after example, and offers his conclusions with such a lack of customary fanfare that its possible to miss the profundity of his achievement.
