Review for Addressbooks Synchronizer by TechByter
Rated 4 out of 5 stars
Unfortunately, I can't edit my previous review, the one titled "I can't make it work."
The problem seems to be that the option to upload on program close doesn't always work. I've seen this with both Macs and Windows systems.
If you make changes, you need to remember to upload the file manually or set the add-on to upload every few minutes.
Overall it works -- just not as reliably as I would hope.
