Summary: A Must Have.
Review: This is a true undergraduate physics book. If you don't already own it, you should. The only complaint that I have with the book is that if used by its self the book tends to become less and less complete as you get closer to the end of the book. And some topics such as magnetic scalar potential (which can be a life-saver) is completely left out of the book. I would seriously recommend anyone using this book to also try to find a copy of the out of print book by Munir H. Nayfeh (Another must-have); it covers the holes that Griffiths leaves out, and it has over 300 worked examples and answers to the odd problems at the end of the book.

Summary: Key concepts of electrodynamics very well explained
Review: This book explains key concepts of Electrodynamics very well, and gives some light into details were the reader can make mistakes. However, it is has not all the mathematical rigourosity like Jackson, but all in all it is quite a good book.

Summary: How does he do it?
Review: Mr. Griffiths must be some sort of a genius. He has written the kind of optimal text on the subject.Never does the momentum drop and that's what makes this text so exciting. Moreover, this book answers doubts as they arise. That is to say, you may get a certain doubt on reading something, just to find that the author answers it in the next line or paragraph. That sort of anticipation makes Mr. Griffiths a king. Great text, suitable for relaxed self-study.

Summary: A book for understanding
Review: This book should be entitled "Understanding Electrodynamics", it
really clarifies a lot of difficult concepts in electromagnetism. Too many books don't explain these concepts or even don't mention them at all. Moreover, the author has the courage to present his subject in an informal way.

Summary: Awesome
Review: This book is awesome. Griffiths has an uncanny ability to anticipate the little problems and questions students will have when first introduced to the material, and he addresses them, if not ahead of time, then right away. At the same time this book is a bible of subtleties and not-so-obvious but enlightening parallels. In short, he doesn't only teach the material in a well-organized and easily understood manner, free of errors, with well-chosen emphases and omissions, and in an informal and natural tone. He also brings the big picture - all the broader and often overlooked links and relationships - into sharp focus.

Summary: Learning electrodynamics incrementally
Review: Several texts I've encountered in advanced-undergraduate levels are set up pretty much the same --- a chapter of information containing a lecture explaining equations and physical principles, examples interspersed throughout the lecture portion, and then about thirty to sixty problems on the material covered in the chapter. So the student eats a big meal --- a lecture and examples on an entire chapter --- and then must digest it all at one time and show what they've learned by regurgitating answers on a piece of paper (to continue with perhaps and ill-chosen metaphor). However, it has also been my experience as a physics student at the advanced undergraduate level that some of the texts I've found most useful have been set up differently --- instead of a whole chapter to digest at once, Griffiths is set up in sections within chapters which have problems of their own. So the digestion of the material is slower and, in my opinion, healthier (in that the student can think about concepts in smaller packages right after they've read them, and then be able to build on that knowledge-base as they continue through the chapter to concepts related to what they've already learned and tested themselves on). Griffiths also has many additional problems at the back of each chapter which are more challenging than the problems at the end of each section, thus pushing the student to an even higher level of understanding. The only grief that I have with this tome is the lack of answers to the problems at the end of the sections of the chapters. I am mainly an independent learner, and answers are very useful, especially when one is first learning a new mathematical technique or trying to master a new concept. While true that he includes some answers to the problems at the end of each chapter, by that point it is expected that I am already familiar with the problem-solving techniques, so they aren't as useful as they could be. I'd prefer it if he set it up the other way around --- answers for the problems at the end of each section, and then maybe only a few answers for the problems at the end of each chapter. All in all this is a good text which will give an undergrad at the junior level a thorough education in electrodynamics. I recommend, however, that the professor use an additional text explaining in finer detail partial differential equations and vector calculus.

Summary: great, friendly, clear introduction to ED
Review: A great text to start with regarding electricity and magnetism (the first part of the book) for freshmen, and electrodynamics (2nd part) for sophomores.
As an introduction textbook it is not as extensive as Jackson's book, BUT it is much friendlier, easy to read and digest, great if you are autodidacts and truly recommended for undergraduate students that suffer from lousy lectures. (-:
The best book to learn from in electrodynamics as far as I know...

Summary: excellent tutorial on E&M
Review: David Griffiths must be the best physics author in existence. His books are always great explanations on how things work. In "Electrodynamics" He introduces concepts without burying the reading in mathematical equations, while at the same time providing solid examples of the subject. I highly recommend this text for anyone who wishes to learn the fundamentals of electricity and magnetism.
Rating:
Summary: A wonderful bridge
Review: I fully agree with the concepts expressed by other reviewers that have rated this book with five stars. I add the following: Griffiths' book is a wonderful bridge between the elementary physics textbooks (for instance, "Physics" by Resnick, Halliday and Krane) and the advanced treatises in electrodynamics (of which "Classical Electrodynamics" by J.D. Jackson is a venerable example).
It is compasionate to the student interested in the subject but who needs more handholding than others more mathematically gifted. A pleasure to read and to cherish. The world needs more David J. Griffiths. A Community College Professor of Physics.
Rating: 
Summary: sub-standard E+M book.
Review: This book seems to have been adopted as the standard undergraduate text on the subject, but it is severely lacking in content. I find Griffiths writing style rather unorthodox, and excessively wordy. The chatty discussions of various topics will leave you dazed and confused, and the exercises leave much to be desired. Also, be warned that there are no solutions for the problems, which makes them useless, in my opinion.
