We've been using them for 8 years for our ad network. It works well and is very easy to use. The UI/UX is not as great as some other networks we have used in the past, but it's still pretty nice. They do a good job of tracking performance with the different ads you're running. They also offer a lot of third-party tools that can help you manage your campaigns. Nothing really. They are a solid partner. You will be able to find many things here that will make your life easier if you need to run an ad network. I wish they offered more advanced features. They don't offer quite as much flexibility as some of the others out there. We were looking for something that was easy to use and could offer us some extra features for managing multiple sites and ad networks.
