| Example product review | Setup took just a few seconds, and it works right away. All my pixels from GTM are now server-side and perfectly connected. So much money saved on ads. | "I don't feel like the service or partnership is as professional or helpful as it could be...just serving as a base-level for our trigger and SMS programs." | "We were having difficulties with accurate and consistent revenue attribution...With Littledata implemented, we now get consistent and accurate revenue attribution." |
| Example support review | The support was very fast to answer our questions and super helpful. Just be careful to check that the events don't trigger twice. | "Wunderkind has been receptive to this feedback... it's disappointing that this has been an ongoing issue." | "Customer support is absolutely amazing... you can never go wrong when an app does what it says and tacks on great service!" |
