Nice book and it can be very valuable, but when instructing with collocations I tend to select examples that arise during a given course, rather than making a course out of it. Using Collind Coubuild online (or any other online site) can do more than this book - going online makes the process student-centered and more active.
I do however see this book as a useful reference to be used from time to time. I simply feel that collocations are better illustrated via online searching and discovery. One strength I guess is that the book goes beyond the word level and has students see patterns in language - and for this it gets a 4-5.
