It's easy to use, very user friendly interface! The system works in every situation I need it too but sometimes when you are not sure if something will work or wont' then this can be an issue for me as my job requires so much confidence with data inputting & sourcing which helps us make decisions quicker at times - nothing really bad just maybe more helpfull hints would have been nice :) If your looking around trying different things out there isn't one program like datasource where all options come together under 1 roof making life easier than any other software we've used previously (at least thats what i think). For example using Datastreams API integration allows users such as myself who donot know PHP well enought o easily add new features via our own code without having t worry about coding errors/bugs etc.
