Has anyone used Backup Buddy?

Has anyone used Backup Buddy? Can you let me know if it works well?

I tried a cron with no luck and came across backup buddy which says it works with MS/MU sites but doesn't support them, of course. I like that it will backup to Amazon S3, backsup the database and the files...
