This is a great introductory module to Basic D&D and B/X in general. I would have loved to give the POD version a higher score, but sadly, the map for the Caves of Chaos appears to be printed all the way down to the spine, and given the binding of the book, a part of the map impossible to read unless you almost break the book by opening way too wide. Another issue I encountered is with the reference sheet just before page 15; both sides of the reference seem to have the printing cut off at the bottom. Thus on the first reference sheet page, the word "Shield" in the armor section is cut off and the information below "Shield", as well as the section underneath "Wooden Pole" on the right column are missing from the POD. Similarly, on the other page of the reference sheet, the last few lines of the wandering monsters (rolls of 18 to 20) are cut off and missing. Surprisingly, this is not an issue in the PDF.
Due to those choices regarding the map for the Caves of Chaos, and the printing errors for the reference sheet, I can't rate this higher than 3/5. The module is still useable, but for your own sake do not buy the POD alone, and get the PDF alongside it to print the complete reference sheet and a useable map for the Caves.
