Average Reviews:
(More customer reviews)This prism was significantly more expensive that the least expensive but is listed as having a book that goes with it. The book is actually about 2 inches wide and 4 inches long and contains so little that its hard to believe anyone could list it as a "fun and informative guide book".
Pass on this one.
