I like that it can be used for any person or business to help keep track of who is doing what in your organization! It's easy enough so non-techie users will also find this useful too!! Sometimes there are glitches when trying out new features but they get fixed quickly once notified about their issue/bug report (and sometimes even without needing an official bugreport).
We use detective as part our security team at work which helps us identify if someone has been using another user account while logged into one specific computer system we have access over - great way not only know where all employees go during working hours BUT ALSO KNOW IF THEY ARE FALLING BEHIND IN THEIR WORK OR NOT.
