The interface is very easy to use, it's not difficult to understand how it works. It's easy to place ads in game lobbies, so that they can be seen by other players. I dislike that you cannot block certain ads from appearing, this means that sometimes you'll see ads that aren't relevant to your game or matchmaking. This is only a minor problem however, and it seems like this could easily be resolved if more people complained about it. If you're looking for a simple ad network to place ads in your games, then this is the one for you! CPMStar allows us to place advertisements in our game lobbies, which helps us generate revenue.
