For a little background, I own a previous paperback edition of this book from years ago which is buried in storage. As I look into making several projects now that my 3D printer build is complete, I find myself in need of a refresher. I was overjoyed to see a new edition of this book had been released and was available on kindle. Now 20 minutes and 14 pages into the book I've given up and will be buying the paperback edition. In those first 14 pages I encountered 2 places where example calculations should have been displayed and an instance where the symbol for a battery was to be shown. All three situations just had a blank space with references in the text to the missing information the only indication that something was missing . As a result it's not worth my time to continue since I'm not willing to deal with the frustration of this which I assume will continue through out the text.
It's a shame too, since I thought the index was well laid out, liked the hot links within the text that take you to other referenced sections of the book and know that the content of the paper edition is probably outstanding. Thank goodness that Prime will get the physical book to me quickly.
04/20/16 Edit: I've raised the rating of this book from 1 to 3 since I received the physical edition of the book which is awsome and I realize the 1 rating was a little harsh. That being said, I firmly believe that if you are going to publish a kindle edition of a nonfiction book, it must be identical to the physical edition. Someone purchasing the kindle edition should be able to receive the exact same information in a kindle edition as in a physical edition. If you can't publish a book like that, I don't think it should be published as a kindle at all.
I've also added a couple of images from the physical and the kindle edition of the book to illustrate the issue that I'm talking about.
