Title: Very Useful.
Review: I got this book for my 15 yr. old son and he uses it all the time. He carries it in the side pocket of his back pack so he can use it easily. He has found it useful in many cases for helping his friends out and working on his various mechanical projects. It has a lot of great info. separated into easy to find and use chapters. Great reference book!
