Rated 5 out of 5 stars

Well, this add-on needs some more positive ratings! It is easy to configure, variable because you can configure it for each calender file separately, and the current version DOES purge automatically.
And the add-on is being maintained, so future versions will have more features!
I recommend it for every lightning user.

This review is for a previous version of the add-on (0.2.5).
