I've been working with the guys for about half a year - I monetize my site with push-ups and subscriptions from zClick, which is also their affiliate.
I can say that the impression of them is positive - the platform is convenient, landlines are added very quickly. They are excellent converters, I think it's the darkening of the screen when the push comes up.

The guys are reactive in the Telegram - and not so reactive in the tickets)
I recommend it, it's a good push network,
