Has anyone worked with Yodo1 Games?

I've got an offer from this publisher to work with them for one of my games that has 300k downloads on ios and 3mln on android (over 3+ years).
Did anyone worked with them? Do I need them?
I've seen games in their profile where some performed bad and some good.
I don't know if it's worth the effort, depends how much traffic they can bring.

Hello , did u tes it ?

Yes, please
