Zindus has completely trashed my contacts in Google. I now not only have multiple duplicates (in some cases over 20 for one contact) but also missing contacts that I'll now have to restore from a backup.
If you still want to try this, I highly advise you to take a backup first. I'm uninstalling mine now.
Chris, if you feel like the addon hasn't worked properly, please file a bug report - http://zindus.com/i/reporting-bugs
