I bought it just by reading the reviews.
Brilliant work done by author. Every chapter is interesting to know the techniques of great companies. It makes us realize that to succeed in business it is not money or power but down to earth attitude. There are many examples but the best one is the example of GE and Coca-Cola. It is very aptly simplified and inculcated to the curiosity and attitude in different avenues.
The book is worth every penny.
