I'm studying out of this book for my intermediate micro course. Simply put, the text is good (but unremarkable) for what it is: a no-nonsense bridge between the usual undergraduate principles course and graduate course in microeconomic theory. However, I can't help but feel that Frank skims off too much math in the name of accessibility. This won't help the reader looking to go further in the subject, i.e., grad or b-school. This would be okay if the appendices packed the math, but this isn't the case: the appendices are on-line at the publisher's web site, which pretty much means if you want to follow the math, you need to be near a computer. A somewhat "mathier" text, that I highly recommend, is the latest edition of Varian's Intermediate Microeconomics.

A must for who is genuinely interested in UNDERSTANDING and ENJOY the basis of neo-classical theory. Better than any other other book!

It's rare to find a text as enjoyable to read as Frank's in any subject, let alone microeconomics. The reader looking for the standard calculus-based, mathematical approach to micro should look elsewhere (Jehle and Reny is a great place to start). That's simply not the point of this text--the point is to provide the insight behind the models, as well as to promote critical thinking about the shortcomings of the traditional assumptions economists make. This text, combined with Jehle and Reny if one desires rigor as well, provides FAR more than any other single or multiple text combination available.
