Rated 3 out of 5 stars

Works nicely with small address books, and really does synchronize them (as opposed to Addressbooks Synchronizer). Yet it ignores address lists and it does not progress on my real address book with 700+ entries and some 20 lists. So I'm back with exporting to LDIF files, syncing them with unison and kdiff3 more or less manually, and then re-importing them :-(
