I became a believer.
I was a believer in First Aid and Blue Prints books that I used for steps 1 and 2. There was no Step 3 First Aid at the time and so I tried this book. This turned out to be an excellent book for step 3 review. It covered the topics sufficiently for adequate review. I used this book in conjunction with "Boards and Wards" and worked questions in the NMS step 3 books as well as the kaplan q-bank. That works. Most say that it is not necessary to spend much time studying for step 3. This is true, but you do need to study some. This book reads quickly and the information is high yield. I highly recommend it and hope that new editions are released over the years.
