| Example product review | "After using Blotout for a couple months, we decided to drop them... Blotout was taking credit for a lot of Klaviyo pixel events that would’ve happened anyway... Event match quality in Facebook was marginally better, but I don’t think it warrants the cost or complexity." | "We were having difficulties with accurate and consistent revenue attribution...With Littledata implemented, we now get consistent and accurate revenue attribution." | |
| Example support review | "Unfortunately, the team... very high employee turnover; it can be really frustrating to have to re-explain things to new reps." | "It took weeks to get a reply regarding a refund... it seems they grew too fast to keep up with customer service." | "Customer support is absolutely amazing... you can never go wrong when an app does what it says and tacks on great service!" |
