The level of support team should be noted especially (at a high level, the speed and accuracy of answers is 10 out of 10) and stability of payments (always on time, even on holidays like the New Year). They always send them on time even on holidays like the Thanksgiving Day. ROI is far in the plus in terms of geo compared to other affiliate programs. Out of the minuses I can mention only the interface, about which they write everywhere. Not that bad, I've seen a lot of them, but there is something not understandable here. Some sections, which logically should be in a different place. Or some filters at the statistics, while you guess what it is, but here you can ask a question to the manager and quickly get an answer and instructions, so it's all the same, the main thing that everything works without drawbacks and other problems.
