I have used it more than a year ago, at which time it was restricted to timeline and pages. It has since added exporting content from groups (and probably others). Basically anything allowed by the Facebook APIs is what it aims to support. The downside is that it stores it in its own proprietary database and needs a subscription to continue to use it (though it's quite cheap, and I certainly wouldn't put the price as a factor against it).
