Anybody tried Heyzapp ?

Has anybody tried Heyzapp already ?
How does it work as standalone and also in mediation with other networks.

I am going to use it with applovin and fan… Any experience from your side ?

How are fill rates and ecpm ? Also anybody knows how fillrates and ecpm are for FAN - network ? (especially brazil)

I like their mediation and integration system. I won’t comment about the rest as it’s relative to each app…
