Exciting, but...
Customer Rating: 
I just bought this, based on experience of Gurstelle's other books ("Art of the Catapult" and "Backyard Ballistics").
I wasn't disappointed at the content, though anybody who has spent time on the internet (especially sites like Instructables or Howtoons) will have seen versions of most of the projects before. The only project that was wholly-new to me was the Mechanical Toe.
What did disappoint was the quality of the book - nice shiny covers enclose dull, yellowing pages. The paper used does not promise long life, and I do not think it would survive if I kept it with the rest of my Making library (in my shed).
So, buy it if you like Gurstelle's style, or if you don't want to spend some time filtering the dross from the Web, but don't buy it if you plan to keep it for several years.
