Momo Cotton review for Elevar Conversion Tracking

To be fair, I am not a developer, nor an engineer. The reviews of the app are good, and the need for good tracking is real. So far I am only trying to perform the set-up of the app, and it is complex and time-consuming. I fear that the probability of breaking the current tracking is higher (e.g. it is recommended to remove current tracking code to avoid double tracking), than implementing the app adequately without the need to pay the 1000$ implementation fee. The app provides tutorial videos, which help but are not sufficient.
