I switched to Payv when they merged with cbd partners.
I'll tell you right away that the transition went smoothly for me personally, all the data, password, balance were preserved. So far I send traffic only on cbd offers from doorways, mostly German on private smartlink.
Out of the pluses: support always responds, I see that they add new brands in smartlinku, on the Germans ratio is excellent, even more.
On the downsides: there are delays with payments, one time they delayed for a week.
