Muy malo, no vine completo, además se demoró mucho más de lo que decía al momento de comprarlo. Solo aplazaban la fecha de entrega sin consultar cómo afectaba al cliente. Yo tuve que presentar el examen sin el libro, porque no llegó en la fecha que decía al comprarlo y después se cambió 3 veces la fecha, casi cumpliendo el mes.

Great read. Tons of info.

Format: Hardcover

We really like this book. A great background and detailed info on this topic. Really like the real-world examples and application. Pretty exhaustive, as far as that is possible given the topic. Also, quite easy to read, although I confess that if from an engineer's perspective.
