5 stars: as the software works and I can tell the workmanship that went in it!
1 star: dishonest advertising. What a disappointment this software is. The descriptions mentions folders many times. It even ones gets really close to real folders. But it is not. It just tags the media and media can be grouped.
So, NO REAL FOLDERS and all your media is still in one main folder.
That might be great if you are on a hosted solution with a small site.
If you host privately and have a large site, then look for another plugin. I ended up with Media Library Folders; which does manage media in REAL ACTUAL folders.
