I've been working with this site for a long time and there are a lot of negative points:
1. In my case, payment is always through a capitalist and not money is added automatically, but through some person who works 5/2, i.e. if I have campaigns and the money runs out on the weekend, then I need to write to support or Putin so that I am given a shameful loan, after showing screenshots about payment. In other sites, everything has been done automatically for a long time, without interacting with any accountant. why there is no such thing is a mystery to me. 
2. Fraud traffic. they often mix up fraud traffic and then ask for reports from the recl and allegedly someone will check something there, apparently they look at how many percent of the fraud was drove traffic into me. 

3. As already written, the traffic goes on and on. then they will be asked to raise the bid. for example, you spin some kind of VPN for $ 13 for three days, the manager comes to you and says, "Client, we are not in the top, we need to raise it to 20. Can we?" and you're sitting there and freaking out at the audacity of such an offer. 

In general, do not work with this grid, there are a bunch of other advanced and stable grids that give swarms many times higher. 

and they also buy reviews here as someone wrote. and promo codes don't give you anything. cheapskates
