We have been cooperating for more than 2 years, our impressions are always positive. WW offers, including LATAM, which is important! Direct rekl by gut, which explains a lot.

You can customize the target action, sources, real-time statistics. It is important that the lk without all sorts of chichi popups, pop-ups that can not be closed, all clean, convenient and intuitive even for beginners.

There is also tracking sources of leads and trafficback. Among the interesting things - adaptive landings and linking the session to the landing page.
As stated, Aff1 has its own call centers located in several countries, whose operators speak the native languages of customers. I haven't checked it myself, but there is no reason not to believe it.

Responsive managers (Nikita, Valeria, Max), communication via Telegram (convenient) and Skype (for archaeologists), in Russian (important). Constantly launch new geos, select optimal rates, pruf. On the offers raise rates if they feel the potential of the source of traffic.

The affiliate has the ability to park domains, there is an API with all the documentation, so there are no problems with customization.

A convenient feature for affiliate marketing teams - Master account, I have not met in other affiliates.

On the site there is an extensive list of partners with various discounts and bonuses: proxy, spy, adheart, cards and so on, there is something for every taste.

Payouts on schedule, often go towards and pay out earlier, on request, but the minimum is 50$.

From the disadvantages I would like to emphasize the bottlenecks that should be worked on:
On the white goods want more variety of offers.
Landings if you use not your own - there are crooked, you need to look carefully.
I would like a system of bonuses and motivation - battle of the teams, bonus store for the best web.
Minimum $50 - for beginners probably not very convenient.
There are no offers of white goods on LATAM.

Overall impressions are positive, we continue to work, everything is not bad.
