Having worked on 3 Security+ book over the past year, this exam cram book certainly has all the major points or highlights in one place. The authors, who have extensive years in the IT industry and the Security arena, have condensed the objectives and given you a tool that is meant to be used as a final stage prep tool.
One thing about Exam Cram books is they can not replace knowledge and experience and if you are looking for the all the test answer, then this book isn't for you. However if you are looking to be able to put the finishing touches on your exam prep, than this book makes a fine addition to the QUE Security+ Training Guide.
One thing that has always impressed me about the Exam Cram Series is the tips and hints throughout each chapter as well as the practice questions, which have excellent explanations with them. This book like other in the EC2 series includes the Prep Logic tester, and as with other books the entire set of questions should be included.
Overall this book not only makes a fine tool for the exam but would come in handy after with the real life exam.

The last one seems really complete and much detail (especially on Cryptography). Seems to be the best if you want to understand the subject and not just pass a test.
Now, for this book - I have a real problem with some of the reviewers. The ones that complain because they say it is not detailed enough, obviously haven't read the 1st couple of pages of the book. The author specifically says that this is for people who already know the subject and that this is just a review of the subject for the test. The ones that are upset that they didn't pass the test after reading this book, obviously missed the boat.
I myself have been reading this book 1st (as I have some experience in field so understand most of what it says) and then go to one or more of the other books to get other views on different topics. I myself want to understand the subject - not just pass a test.
