Useless: springs were not included.
The main photo shows an included spring, which is of course needed to use the solenoid in any reasonable application . I ordered two of these items but neither package included the spring.

The subtitle tells everything you need to know.
I bought this book to learn how charlatans word the disclaimers that protect them from being sued by the gullible fools who are harmed by their nonsense. This book provides superb how-to-do-it examples. I enthusiastically rate it A+++!

Classic
Despite its age, this is a classic that should be read by everyone working in and around the field -- even the most up-to-date students of computer scientists still have much to learn from Feynman.
