I bought the Grim's Amazing D100 Tables Complete 2016 Collection [BUNDLE], and I'm adding this review to the included PDFs.
These are all quite lame. I would say $0.50/ea is a generous amount. Spelling, gramatical and punctuation mistakes. Some of the PDFs are just missing lines; it'll go from 40 to 42 with no gap, for example. Not a lot of through went into any of the suggestions that I've come across. It's a adequate place to start for new DMs, but not much more than that. I would especially avoid any of the "names" files as online generators could do the same, possibly exactly the same...
PDFs are: cover page, summary page, two or three pages of list in large font, and three or four pages of ads.
