Very good product. Worth every penny I paid for it.
The only reason I purchased this product was because it was the cheapest one listed here (who can blame me considering the rising prices of hdd's). So I didn't expect much. But this is a really good piece of hardware.
It comes with its own software which checks for firmware upgrades and software updates regularly. The software itself can take an entire backup of your hdd, a scheduled backup and most important of all -"specified folder backup and synchronisation". That takes the cake :)
