I like that it is easy for me as an admin user of our site (and my customers) because they can see all their shipments in one place! It helps us keep up to date about what's happening at any given time - we're able solve issues really quickly when things go wrong or if there has been some delay/late delivery etc.. The reporting section could be improved but overall this system works well enough so far!! We've not had many problems using them apart from minor glitches here nthere which have usually resolved themselves without issue after contacting support team via email / phone call :).
