I work in affiliate marketing for more than 2 years, today I work with adverten, according to my observations, is one of the best affiliate programs. Tested about 10 different affiliate programs during this time, on Adverton almost all Tier1 converts by 10-20% better than on other affiliate programs. Some of Tier2 and Tier3 convert worse. Therefore, for the quality of offers i give them not 10 stars.
For the other moments there are no questions, managers almost always respond quickly and even on holidays sometimes respond, and change the offers if there is a drawdown on the profitability.
