I am now using this to sync my music files since windows media player sync doesn't work right with my mp3 player for some reason. When doing this I have found i need to use the switches --delete:y --overwrite:n -t -c for the utility to have the effect I want.
Have been using version 2.00 for a couple of years to keep a backup on an external drive. Simple to use and I've never had any problems with it. It perhaps lacks the efficient delta copying of rsync but for the amount of data I backup (a few hundred GB, most of which remains the same between backups) it's fine and I prefer the simplicity anyhow.
