Yes, we promote both and yes they are reliable and have good affiliate managers. No problems with delayed payments. No negative feedback from players.
Both have moved over to income access software now, so they have some decent online stats.
We have always found conversion for Coral to be very good for us – we have mostly UK traffic. How well the product actually retains and monetises though is open for debate.
We have less experience with Eurobet in terms of volume but the few non uk accounts we have gained have been profitable for us.
