After installing this plugin, I ran into MANY bugs. The automated setup process just hung and ended up failed, after setting up the site manually, the plugin would not enable. On top of the many bugs, there was an annoying box that kept asking me to buy the $99 version. DO NOT buy the $99 version as you will only be ripped off.
After looking at this company's site and the little support they provide, they are clearly just wanting to make a profit instead of providing a quality site optimizer.
