I have just started to promote them in this month too, and I have similar numbers like you tryme, so far very great clicks/signups ratio, but no depositing players yet.
They are on my site for a week or less, so it’s not enough time to tell anything.
I have signed up as a player too with their properties, but I didn’t get any newsletters or such, so it worries me that player retention/conversions could be a problem without communication.
As I said I just started to work with them, so the final verdict needs more time.
