I love the way Kendall breaks down sleights so that you can learn them easily. His book isn't unique in that respect, but certainly unusual. He might, for instance, have you start with fewer cards than are required, then master a tiny piece of the move, and so on, until eventually, when he teaches you how to put the pieces together, the move isn't so hard to learn. He's in good company -- Michael Close, Aaron Fisher, and Carl Irwin do similar things in their teaching.
Kendall is opinionated but in a good way. He explains different ways to do a part of a trick or sleight and explains why he prefers one such way.
