The ability to track all of my campaigns in one place, as well as being able to see what channels are bringing me revenue is great! I wish that it was easier for users who don't have technical skills or know how things work under-the hood (like myself) would be more intuitive with some features like creating custom reports/dashboards etc.. Overall this has been an excellent tool so far though!! It's very easy once you get used too everything about using adcenter - from setting up your account through adding new adsets / creatives & tracking them down via reporting system :).
