Query: A very bad book

Poorly written book with very poor pictures. I hoped to find there much more information than in very compact (but as I now could see much better written) manual of F100. Instead I found unclear "explanations", not finished desriptions and much less technical information than in the manual. (e.g. no errors description at all)Don't buy it! Read carefully the manual, you will save some time and money.
