I've been working with them for six months. Not everything is perfect, but without any critical problems. According to the main parameters, everything is good. The payouts, the bids, the choice of offers, there are no complaints. If you're in the black, minor shoals are tolerable, I think so.
Plus, they give you access to interim analytics from the recl itself, which allows you to fine-tune your target and raise your cr. Without it, there would be a blind bay.
