Rated 4 out of 5 stars

Works very well and compliments for being already compatible with TB 78.

As of today it's practically the only working alternative to gContactSync (that is not compatible with TB 78 - hope it will be soon)

I give it 4 stars because it would be perfect if it could handle and sync contact categories with Google (even if we're aware of the problems - Google side)

This review is for a previous version of the add-on (51.7).
