Highly reliable synchronization tool

I was looking for a simple, straight forward sync-app that would allow me to manually synchronize several folders on two different external hard drives - and Sync Folders Pro does that flawlessly. I dont use the auto-sync feature, so I cant say anything about it, but I can highly recommend this app to anyone wanting to sync folders manually.
Theres traditional mirroring & bi-directional sync and tons of preferences you can tweak to your liking. Also, it looks like Sync Folders Pro is in constant development - a lot of features have been added since I bought the app more than a year ago and the developer seems determined to make the app better with every update.

Sync Folders Pro is fast and stable and I feel like I can trust the app completely - and thats one of the most important things a sync-app has to accomplish :))
