The ability for our team members who are located across multiple time zones to collaborate easily while maintaining security of their work files has been amazing! There was nothing I disliked about this product at all - everything worked flawlessly from day one.
We have used other products that were not as user friendly or lacked features we needed such as file sharing capabilities but Auro handled those issues well too by adding additional functionality when required. It took us less than 1 month to get up and running using only 2 people (1 admin & developer) so there wasn't much training involved either which made things very simple.
