In general I like to use Adjust. The cost benefit is very good, and the tool is very complete.
Their support is very good. Always very available and willing to talk and help.
Adjust is very solid product and we’ve never been faced related issues coming from it and helps us to analyze our user's behaviors.
User interface is a little difficult to navigate, multiple clicks to get to one action. Also, set up can be difficult for engineers to nail the first time.
And the lack of a local payment method, generates many unnecessary tax costs.
It's a necessary evil when you need attribution data. There are others, but most of our partners use Adjust.
