I like that it is very easy for me as an employee of our organization, because you can easily control all aspects from one place (mobile). Also they have good customer service! Sometimes there are some problems with their system but this happens rarely so far in my experience - still not perfect though :) But everything works fine at least 95% time or even 99%. We use them mainly during construction projects when we need help keeping track what needs attention by contractors/subcontractors etc., also sometimes just general information about work done eithin project management software helps us keep things organized properly.
