The terse description could easily mislead someone into thinking they get ALL of the profits from the links, when in reality, they split the profits 75/25. You will find this info if you go to the trouble of looking at the FAQ. All other plugins I have seen CLEARLY ASK if you would like to split the profits in the setup process, or take no profits at all.
Besides that, the only problem I had was that no links were created in any of my posts. In other words, it doesn't work (so I guess there weren't really any profits to be taken).
