I'm using pudding to monitor all my campaigns with their reporting system, which is very useful for me since i can access them from anywhere at any time! It's also easy to implement an API if needed. Honestly haven't seen anything that I dislike about this product so far, it has been working well as expected when used according to its tutorials, instructions and documentation provided. If they would add more features or better explain how we should use each one of those (not just tutorial), that could be cool too! We're solving our problems related to targeting different audiences, campaigns monitoring, getting reports etc., everything was easier when managing multiple accounts through tools like this one.
