Looking for user advice

I am looking at a program called Keywordelite. It is supposed to help pick good keywords to optimize a web site to bring in traffic through Google search and pay per click. My research on it looks good but I am trying to find someone that has it and is using it. I want to talk to someone that has real experience with it and see what their opinion is. The ads from the people selling it are supposed to put its best foot forward but I trust the opinions of actual users more. I am just funny that way.
