Very beta-like (or even pre-beta), bad looking version. In my 15minutes test by just removing file from the local folder during sync I caused a full stop for any sync operations. Restart didn't help, the only way to "fix" it was to remove data store on SFTP side and re-connect clients. Sync speed is low (seems to be limited to something around 3MB/s, on LAN). All operations seem to be sequential. Integration with Finder just a joke, most time it doesn't refresh green/orange badge automatically. From time to time client shows odd messages like "over limit, upgrade plan" (what limit?, what plan?). In my opinion - doesn't worth any money yet. I'll stay with btsync for sync and seafile for dropbox-like.
