It's basically Appendix A from the AD&D 1e Dungeon Master's guide rewritten, possibly with more detail than you actually want. I would encourage you to provide the monster and treasure generation tables from whatever system you're actually using(Labyrinth Lord is the default system and it has you covered there) because what has been provided is rather minimal. Just enough to get you started.
I should also say that I dislike the campaign setting but this is not an obstacle. Players will doubtless use their own imaginations so a detailed review of it is unnecessary. But the dungeon generation tables are just fine, although they could have been better arranged (print them and paste them together in a way that makes it easy for you.)
Anyway, the price is right. So if a solo or GM-less dungeon crawl is what you want you should be able to get five bucks worth of game play from this product.
