Excellent product, I love it! Except for the relatively mediocre cover, it's like the old Fiend Folio done right! That is, a Fiend Folio with more interesting monsters. The layout is top notch, and the art reminds of old school monster books. Excellent, I love it. It's one of the very few OSR books that I later intend to buy in printed form (POD). If only it could be released in hardcover (I only saw it in softcover at Lulu), that would be great...
I only have a minor bad point with this book: It is dual-stated, but for games that are very similar (i.e. 1e/Osric and basic/Labyrinth-Lord). Personally I could use a monster book that has 1e/Osric stat-blocks with both games; for me the basic/LL stat-block are useless.
