I like that it's easy to use, so when you have traffic coming from many different sources (directories/webmasters) having one place where all your data goes makes sense for me! So far no complaints about this platform as we've been using their service since 2013 without any issues at least in my experience with them.
A couple of years ago there was an issue related to "popunders" but they solved quickly by giving us more control over our popunders settings which has helped reduce some ads being served too often but not always needed - just what i need :) If someone wants extra functionality or services beyond normal reporting then perhaps look elsewhere because these are exactly how I wanted things handled. It gives good insight into ad performance across multiple networks including direct links, social shares etc., allowing better decisions making process regarding those areas!
