I've been working with Evadav's traffic for almost a year now. I use the services of a personal manager, who helps me with the settings of each campaign. It is very convenient, because the set of tools is very large and is constantly updated and upgraded. The opening of the last month - auto-rules and postback. Improved my status at times, removed illiquid leads, campaign performance has increased by 40%. I started a year ago from ridiculous amounts: Now investing from $ 2,000 per month, all investments are paying off at a superb pace. Imho, the help of a personal manager is always relevant, I advise you not to miss this opportunity.
