B. Pros
What I like about SyncMate is that it provides possibility to sync lots of devices with my Mac (I have blackjack samsung, Galaxy tab, MBP and Mac mini and the necessitiy to keep data in them up to date is crucial). And the best in SyncMate is that data can be synced automatically - that's really awesome!

C. cons
I do not like its interface...Come on, eltima, this is an app for Mac and it should look like an app for Mac:) What else I do not like is that I cannot sync in background. Autosync option is nice, but a little bit cripple without the possibility to sync in background.

D. Summary
Despite interface and impossibility to sync in background, I like SyncMate. It has made my life really easier. I like that I do not need to enter the same contact or event on all my devices (this was a real headache before) and can sync them. It was not easy for me to understand its functionality until I've read the user-guide and test different features checking each step in manual or contacting tech support. But now everything works like a charm.
