We've been using this software since 2015 with no issues at all! It's easy enought anyone can use it without any training or prior experience in advanced marketing tools like Google Analytics 360° View (or similar).
The support is always available if you have questions about how something works - but also when there are problems within your account/data set up etc- so we're very happy here!! There isn't anything I dislike as such apart from maybe some minor UI changes over time which has made things easier than before. This product does exactly what its supposed to do; give us an overview of our overall data across platforms including online activity too.
