    Works great, looks great, simple as can be. I rarely connect my phone to my PC to transfer stuff now.

    My sync was working perfectly until the day I upgraded desktop app to 1.4.75. Now my GUI is all messed up and sync is also not working. Support people also not responding properly. Otherwise this app is greatest in this genre.

    This app is perfect! It does exactly what it is supposed to do. I use it to sync all important folders on my phone with my RAID1 (mirror) array at home. That way I'm not bound to use any specific cloud service for syncing stuff. Now I have lots of space left in Dropbox, GoogleDrive, OneDrive, Copy, MEGA, Box and others.
