As a PDF, reasonable quality. Has that 'photocopied' look of scanned products but has all the pages are present and readable.
As a product, quite good. Five seperate adventures are given, each one introduced by a treasure map, riddle ot other clue that can be planted in an ongoing adventure to provide the segue.
By todays standards, the adventures are a little unoriginal and dated (and would obviously require updating if you were playing 3rd/4th/etc edition) but all seem quite solid.
