Setup was very easy, and the interface was very intuitive.
However, it just doesn't work. I expected that when I merged the two address books, I would have some duplicates and maintenance to do. In my case, almost all of my approximately 150 Google Contacts imported into Thunderbird without a name. I now have a mess of a contact list, and I am afraid to try and repair it at the risk of losing any of my data, because it appears that something as simple as the First and Last name fields do not transfer.
Adam, Google only activated support for first+last name sync a little while ago, the addon doesn't support it yet but it's on the http://zindus.com/i/roadmap
