A great little collection of devious dangers to toss at your players. Sure, some of the ideas are far from the most novel of all creation, but I feel like that's a good thing! The DMG woefully leaves out many of the tried-and-true stand by traps, and this little product means I don't have to stat them out myself! Awesome.
Also, major kudos for the publisher's attitude of showing it all and letting the consumer decide it its worth the money. I really do believe that people will pay for content if you prove its worth the money. It worked on me! I grabbed the diseases supplement, too!
