I like how easy it is when adding new campaigns or changing existing ones! It's very intuitive as well - not too much learning curve required if you're familiar w/ other SPA tools in general use today such has Google AdWords / DoubleClick etc.. There are some things that could be improved but nothing major by far so no complaints here at all :) Have been able t o create custom video ads without having any previous knowledge of coding & HTML5 development skills needed previously using more traditional platforms would have made this difficult before now!! Great product especially considering its easeofuse compared against competitors who require deeper technical skill sets than what we had available priorly.
