I used them on my arcade a long time ago and was getting like $1.5 eCPM. But then half way through the month it dropped to $0.03 eCPM and I dropped them before making payout. Can anybody post their experience with them? I am thinking of trying them again but don't want to waste a weeks worth of earnings if it goes bad. Also I can't find what their eCPM consists of. Does anyone know if it is CPC, CPM, CPA, etc?
