Fantastic Product, I use both the Activities Sync and the Outlook Plugin on my PC and Thunderbird plugin on my mac and cannot fault any of them. They all work great, never had an issue with any of them except one tiny blip when setting up initially (my fault) and the support from Opacus was amazing. Basically for the price I couldn't think of a single thing that should/could be improved.
The program was working great for about 2 months and then it quit working. We have attempted to contact them numerous times and no one is responding. It sure sucks because when it worked, it was great. I wish they would get in touch with us and fix the issue.
Update: they got back to us and fixed the issue.
