I use it, but as a back up tool.
It is not my only back up tool.
It is super convenient in that a person can right click the file and get a list of versions.
But as a version management tool? Pretty weak. Most version management tools allow notes and etc.
For version management, suggest you consider embracing github and git. It is annoying and confusing, but after a while it kind of works. And everyone is using it.
