This book is fantastic for medical students needing help with differentials for patient cases and portfolios. Studying for finals, I also feel the detail is at the right level for this and I have found it useful in the clinical context when faced with different symptoms. I have given this 5 stars as for this purpose as I feel it meets the criteria extremely well.
I had hoped to find a very detailed reference book, having perused an edition from the 1970's. This will be great if you are a medical student but isn't a postgraduate text, and doesn't have some of the things you will find in the simple old oxford handbook.
