What is Reddit's opinion of Schaum's Outline of Theory and Problems of Combinatorics including concepts of Graph Theory?

From 3.5 billion Reddit comments

I have not tried this specific book, but I have had good results with other books in this series:

In my experience these Schaum's Outline books are written by competent professionals, have clear, direct explanations, and many problems both with and without full solutions.

Also, if you get it and you don't like it, you have wasted only about $20.

Schaum's outline is introductory, and it has a lot of example problems.
