The author is generally vague and in many points loses his train of thought and jumps from one topic to another. Nice stories and historical references. Light and good for an introduction to basic concepts but at a very high level, don't expect technical terms, etc. Which is also expected of course since it is written for someone who has not studied economics.

Very sturdy, very good mechanism, easy to assemble. Just got it, so time will tell.

Very good read, from simple concepts to more specialized issues that made me constantly google. An introductory book to the world of astrophysics.

It lasted for a year. Don't let them tell you that it is durable and that they tested it in extreme conditions and nothing happened. Of course, it doesn't have a warranty (only three months from the company). Pico again.
