Query: glossy well photographed but low on usability

most of the effort here has gone into the design and photography, almost every massage tip is hard if not impossible to understand correctly.there are complex instructions which mean nothing, no diagram to explain what is meant, just a photo which doesnt tie in, you have to guess what is meant in nearly every example.this is not a good way to pick up massage techneques, picked up a few tips but overall disatisfied.
