This product was really cheap, so I don't feel ripped off. However, this product fails at it's stated task. It makes monsters that are just as uniform as the method in the Monster Manual. I tried to use their formula to create an Epic level solo monster, and the stats aren't any better than the one I made using the MM. Some of the ideas within are good, and it includes a couple of new monsters. I can hardly say it isn't worth the price, but don't expect it to fix all your home-brew monster needs.
