Well, as far as law books go, this one is as good as any other. The Legalines guide has helped me get through this material as well as the Gilberts.
Casebooks aren't exactly known for their entertainment quality - as this one is certainly no exception - but it covers the material in a thorough manner and isn't too difficult to understand.
My biggest complaint is the tiny typeface used for the Notes following each case. My teacher concentrates quite a bit on these extra factoids and the tiny print is a bit of a strain on the eyes (especially at 2:00am). Otherwise, this book is pretty much exactly what you would expect from a Conflicts textbook.
