I looked at the previous reviews and in all in all there is nothing surprising about it, because affiliate marketing (affiliate marketing) first of all is very complicated, and secondly it is different for everyone.
I have been working with propeller for more than a year. Before it were almost all sources of pop traffic - PopAds, PopCash, Clickadu, Adsterra, Zeropark, etc.
So I almost completely switched to propeller and there are several reasons for that:
1. the excellent managers (at least mine are exactly top), who understand perfectly what I need and can even tell me something new.
2. The interface of the personal account is modern and not overloaded
The campaign moderation is maximum of 1 minute - that's something (hello to the rest of the traffic sourses).
4. CPA Goal - no comments here, those who understand how to work with it, knows its benefits very well.
5. The last point should really be put in first place - the almost total absence of bots. And this is not an unfounded statement, I use custom events in Binome for such parameters as: the movement of the phone, rahigraniya in social networks, screen resolution and other chips, which you will never find in the publisher.
And regarding other sources, I don't create blacklists at all in propeller on bots, only converts or not.

But I will not praise propeller too much, otherwise everyone will run there and the bids will jump on many geo. Although, as I said before, affiliate marketing is difficult enough and I've seen quite a few people who gave it up, so not all newbies are good at it.

Screenshot of Binom for last, so there are no questions about my experience (only propeller traffic here):
