has anyone tried using them? Was it useful to generate installs and/or make money from them? I have a game im working on now and im implementing admob as a revenue source but a revenue source is no good without a significant number of people playing the game.
I didn't try them, but they are just an offer wall kind of thing. Which in my opinion is just incest You pay me and I pay you... And you have to install an SDK just for trying them.
Well If you are running a freemium game it may be a little different. It may generate installs which could lead to more revenue beyond the 1 for 1 install price
