The best part is that it's so easy to use, any user can do this just by clicking few buttons without being an expert in Doc management software like Adobe Acrobat Pro or MS Word etc., I don't really have anything particular dislikes about the product but if you want something very specific then you might find difficulty with their support team.
It does all what we need most of time - doc managment & version control system for our work projects/documents which are stored online as well as offline at my office storage location.
