Rated 2 out of 5 stars

Worked well for a long time but in last couple of weeks have lost all my addressbooks (with thousands of entries).

(Backups you say, yes, that would be a good idea.)

Anyway, appreciate the hard work, and have appreciated the usefulness, but can't recommend at the moment. Take care.

This review is for a previous version of the add-on (4.14).
