The most important thing is that it works with all versions of sharepoint, from 2010 to 2013.It also has very good support team which can help you instantly if there are any issues. It's not free but have enough options for small organizations as well where one person cannot install everything by himself. We use this tool in our organization to view files online without using local drive. Its really helpful and easy to use software. Also its saves time when we need to access file remotely or at office place.
