I like that it automatically categorizes my ads into different groups by keywords so finding what ad works for me can be done in just seconds instead of hours or days - which was always very frustrating when working with other platforms! It's also really easy to create multiple campaigns at once (versus having them all run separately).
The interface could use some work but there are plenty things they've added since launch as well making this an already great product even better!! There aren't many features left now after adding new functionality over time such as multivariate tests etc., however these don’t seem too hard/expensive/complicated either way if you have someone who knows how do add those options back onto your account easily without needing support from their team every step along the process :).
