I installed it and it totally locked up my login to the dashboard and scrambled my formatting on the basic wordpress twenty eleven theme.
It put new pages and a dozen tables in the database and some of them duplicated existing pages. Epic fail and this has cost me a ton of time to recover the data, re-install and add the data back. Plus fixing this database now is a huge task after the plugin totally changed the tables and data in it.
The worst plugin experience I've ever had after six years using and building wordpress sites.
