TestFreaks posted a review on the Rebit 500 GB Multi-PC Backup Appliance

Thankfully Rebit implemented similar features from Time Machine for use in their PC-centric devices. While the user interface is not as polished as the Time Machine's, it performs almost all of its functions plus a little more. Rebit allows the average PC user to easily backup and restore files with minimal difficulty. "Ridiculously Simple Backup" is not just a slogan; it's the way the Rebit works.
