I saw the first comment by Seth Cartens, and how the author marked his plugin down because he doesn't take constructive criticism and that was very childish.
Anyway, this is my honest review.
This plugin was simple and easy to use, but too simple. I couldn't find any information on how to redirect every page of the site to a specific page defined. My requirements needed the entire site redirected to one page, but if I wanted to set this up I would have to put 18 different pages in (what if I miss one?!).
18 "possible redirects" are cool, but what if I have more than 18 pages?
It has it's limitations and I think the developer needs to take the feedback on the chin and look at developing the plugin into something awesome.
