Rated 5 out of 5 stars

After I received a TB auto-update to 7.5x I had to search for a new gmail-sync tool. I found and tested CardBook. It's a modern smooth working tool and I hadn't a single problem.
I normally don't write reviews except when I'm very enthusiastic. I hope this add-on stays !!

Thank Philippe.
