Hi,
Thanks for the interest in Facebook Events Importer.
Yes the plugin does work.
– If I import events, can I edit?
The importing process creates an event on your site independent of Facebook so you can make all the edits you would like.
– When I edit and event, if I re-import events, the edited events will be overwrited?
It will no reimport an event that has already been imported unless you delete the event from your site. It does not overwrite or sync existing events.
I would recommend checking out this page to see how all the features work:

Let me know if you have any follow up questions.
Thanks
