Review for gContactSync by davodavo
Rated 5 out of 5 stars
This thing is powerful and flexible...and it has many options that may not be right for you. Sometimes, it's modes of operation can do scary things---you HAVE to read the instructions AND think before you do massive syncs. But once you get the settings right, this thing is pretty reliable and does a better job than the Zindus plug-in did.
