It's easy for me as an advertiser because I can quickly upload my ads into it with little training once i get used to how everything works! They also have some great tutorials if you need help or want more in depth understanding of certain features - very helpful when trying new things out like reporting etc.. Nothing much really but this is such an amazing tool so well worth using especially considering its free!! We are able to see our ad performance at any given time which helps us understand what we should be changing/changing before running another campaign (which happens quite often).
