I work mainly with India and Bangladesh. 1win has just good volumes on these geos. At the same time, the app is normal, tracking does not steal leads. I am very pleased that there is a separate office with in-depth statistics, everything is visible from the sources. The personal manager is normal, not a bullshit blogger, solves questions about creatives and promo codes quickly. On the drawback, some African geo conversions are still a bit crude, but they fix it. In general, for professionals who drive traffic high-quality, one of the best partners on the market.
