This dungeon was randomly generated by http://donjon.bin.sh, as the bottom of the PDF says. As such, you can get a good idea what the product is like by using that site to generate a random dungeon. The theme for this one is undead, as the name might suggest. Ironically, there does not appear to be a Wraith Knight in the dungeon.
For $1, this product will certainly save you the trouble of fooling around with the parameters of the random generator and then downloading the artifacts from the web site. However, the PDF included wasn't even edited to fit the page correctly (the last entry has a line that is split between two pages, making it almost illegible.
I can't recommend this product unless you find you have trouble getting random generators to work for you. I'm giving it an extra star because at least the price is right.
